ok for the details about changing server, I'll reread this if I have a problem in 1 month 
12/10 support o _o

The impressive answers o_o

I knew about paying services which accelerate transactions but I prefer not use them for now since I only have ~20$ of btc (maybe there are free services too but I'll see later). I Would like to have more but the famous online service doesn't confirm my account after 2 weeks ;_;

I sent more in the second transaction because I got some satoshis between both.

Anyway, in a first time I guess I will wait one more month and maybe the network will forget it. If it doesn't forget I will add more fees to confirm the transaction.

Thanks , at least now I'm sure of my options.

Thanks for your fast answer.
You know everything o_o I only have the first one left in my wallet.
If I understand your answer well my only option is to right click it and "add more fees".
Is there a way to delete/cancel this transaction ? if not I will add more fees.
Maybe If I wait more it will be auto deleted but I don't think so.

hi,
I have a replaceable transaction since more than 2 weeks which seems to be dead.
I would like to remove it since I can't double spend with message "insufficient funds" because of this transaction.
transaction id : c3c4a4510795bc28850a183fb11c4bdb9f24d904a87f40cea5b8d834949de265
Thanks.
