Many thanks to all ! 
Past days, I deleted the database folder and restarted Armory, reloading all the database.
There is now 486 064 blocks and I could send with success last night a bitcoin value to a trading plateforme.

BitcoinQT got 485 623 Blocks right now so it is ok for BitcoinQT but not in Armory.
What do you suggest ?
May be it is a matter of directory, as I moved recently (see above in my posts) from one directory to another but when I have a look Armory and BitcoinQt point both on J:/bitcoin
What is surprising is that it seems to be fully ok for Armory that is online despite a number of blocks less important

My BitcoinQt target is :  "C:\Program Files\Bitcoin\bitcoin-qt.exe" --datadir="J:/Bitcoin/"

Hello,
I try again right now and I have the same issue with the same message : The transaction that you just attempted to broadcast has failed with the following error : Missing inputs

To answer your points and as far as I understand :

Now all seems to be ok with Armory Online/Connected and with 398092 blocks. I've got no other message in Armory
How could  I check/find what is wrong in Armory or in the blockchain data ?


I want to send only 1/3 of my balance. By the way I've been trying to use the MAX check box to test and I have the same results. Concerning the fee, I've been using 60 sat/byte and 200 sat./byte with the same result.

I have the same issue than yesterday :
The first time I try to send bitcoin to a valid recipient address I have the error message : The transaction that you just attempted to broadcast has failed with the following error : Missing inputs

For the second try, I have the "Coin selection failure" with the message "Coin selection failed with error : Invalid spend value"

Could you please help, knowing that I've done all that was suggested above (including 60sat/byte for the transaction) ?

Thank you.
After many issues I succeded to move the data to a new disk past days ...
... and this morning to erase the old transaction.

Now when I try with the same previous recipient address that is still valid until tomorrow afternoon, I have the "Coin selection failure" with the message "Coin selection failed with error : Invalid spend value"

I will wait for a new recipient address tomorrow night and do a new try ...

The issue is that I don't know how many GB it still really needs (even if I saw the value of 160GB globally on some sites) 
I had 120GB free few weeks ago on my "Windows C:" disk with Armory already uptodate and now I have only 4Go on this disk ...
My %APPDATA%/Roaming/Bitcoin directory is currently around 117GB

I'm going to move it on a new disk. How can I do it properly without restarting from scratch, knowing that Bitcoin core node is currently updating ?

Many thanks for your reply.

After your reply, I've done step 1,2,3 as per your proposal.
Concerning step 4, there is no "mempool.dat" in "%APPDATA%/Bitcoin" directory (or subdirectories), so nothing to delete on my side 
From step 5,  I only closed "ArmoryQt.exe" only due to the following elements :

As per your "intuition", Bitcoin core node was not up to date, so I updated it (I would have imagined that I would have seen before an error message from Armory if the Bitcoin core node was too old).

Currently, Bitcoin core node is updating blocs for hours ...

Because my SSD 256Go (Windows drive C) will be full very soon, my questions are :
- Why do I need to update so many blocks (weeks), as my Armory wallet 0.96.2 was already updated ?
- Will Armory wallet update again for hours after Bitcoin core node blocks update ?

I try from June 2017 to move my Armory bitcoin from my Armory wallet to (e.g) paymium or bitcoin.de.
I checked each time that the recipient address is ok.
I had some error messages in the past and I updated twice from last Armory version (in July and recently). Now my version is Armory 0.96.2.
I’ve been trying to increase Tx Fee paid. Now it is 0.005 BTC.
I enabled RBF.
I’ve been trying many times to bump fee with my transaction. I tried to force a script type to P2PKH.
I had several times to erase unconfirmed transactions, to analyze the DataBase again ….
Information from my last transaction are below and still not in the blockchain :
------------------------------------------------------
Id           9030c622b4b6559ae91f3601fef419de495ac55362320dffe72ae6bbd5046b0c
Version   1
Hour       Bloc 398092
Time       2017-Sep-08 07:04pm
Block number   Not in the blockchain yet

Tx Fee paid  0.005 BTC

------------------------------------------------------
I check it in https://blockchain.info/pushtx and while the “Decode Raw Transaction” from https://blockchain.info/fr/decode-tx seems to give a valid format, I’ve got the following message  :
Validation Error: BitcoindException(super=com.neemre.btcdcli4j.core.BitcoindException: Error #-25: Missing inputs, code=-25)

I'm not a BTC specialist and I've been doing all these tries after research on Internet/forums.
After 3 months of trying, I feel really as if it would be impossible to use my money  … Could you please kindly help ?
