Well then the good news is you have access to those 25.912734 BTC the bad news it is not ~50 like you thought (but then it never were).
The problem is these flawed transactions (you actually tried to double spend you cheeky bugger
) are in limbo. If you want to check see
http://bitcoincharts.com/bitcoin/txlist/ . That is a list of all unconfirmed transactions and if you control+f for T1, T2, T3, TA, TD (well the codes for them of course) you'll see them in the list (since March 1st).
To be honest I am not 100% sure how we can fix this (I am very sure we can though) so I'm going to suggest some options which in the very worst case won't work.
1) Do you have an old backup of your wallet.dat? If so, this is what we'll do:
A) Close Bitcoin-qt
B) In the C:\Users\me\AppData\Roaming\Bitcoin directory rename the wallet.dat (do not delete it to be safe, just rename it).
C) Copy and paste the backup wallet.dat to this directory
D) Start Bitcoin-qt with the rescan command
E) If all your Bitcoins show up as confirmed, create a new address and send them all there. (We do this because eventually your client would receive all transactions from the network even unconfirmed ones and then you would again be unable to spend the Bitcoins)
If you do not have a backup or step 1 didn't work we'll do the following:
2) We're going to export the private keys from 1CVX2A8dEPJnV62ey7kEuoNhuAUKvJrDLj and 1LkJVtqoVLKKMsUFrCLnqZ8Vxfmnjs8MSY , create a new wallet, import the keys into the new wallet and move the coins.
a. Again open run the deamon and start the other command prompt
b. <optional if you have encrypted your wallet>. Run: bitcoind walletpassphrase PASSWORD TIMEOUT (where PASSWORD is your password and timeout is the time in second to unlock your wallet so we can attempt the next step, 20 seconds per address should suffice)
c. Run: bitcoind dumpprivkey 1CVX2A8dEPJnV62ey7kEuoNhuAUKvJrDLj
d. Run: bitcoind signmessage 1LkJVtqoVLKKMsUFrCLnqZ8Vxfmnjs8MSY test (note: if you are to slow you may need to repeat step b)
e. Copy and paste the two private keys to a notepad file
f. Stop the daemon command
g. In the C:\Users\me\AppData\Roaming\Bitcoin directory rename the wallet.dat (do not delete it to be safe, just rename it).
h. Start the daemon thread (do NOT copy a backup wallet.dat to the folder, there should be not file named wallet.dat there so the client will create a new wallet)
i. Run the following command: bitcoind importprivkey privkey1 (the first private key you copied to the notepad file)
j. Run the following command: bitcoind importprivkey privkey2
NOTE i and j may take a while
k. Now see if you have access to the funds, if so create a new Bitcoin address and send all your funds there for reasons explained above.
Hopefully one of these two methods will give you access to your coins again.
Beware:
1) Do NOT share your private keys on this forum. Anyone who has them can take your coins
2) Do NOT save the notepad file with the private keys as this poses a security risk. May be it's best to just avoid using these addresses anyway.
Finally: How did you guess wachtwoord was Dutch (it's Dutch for password)? Dutch relatives?
