i have the backup folder that contain wallet.dat.mmddyyyy files and when i copy those files in the new folder... they are beeing ignored. When i restart biblepaycore they are automatically deleted and only backups done after 1.0.7.1 update are kept in the folder.
Anyway bro thanks for trying to help and all your efforts to make this wallet better but this is the first time i'm troubles with gui wallet.
With all the updates every 2 days lol

i will just use it for mining and store the coins on the site (i know it's note safe) i will transfer them to a papaer wallet at some moment.
Just to be sure, you when you copy one of the backup files ending in mmddyyyy, you do need to rename that file to wallet.dat.
So cut and paste your current wallet.dat and move it to your desktop (or documents folder). Delete the other .dat files from the folder. Then go to the backup folder, cut and paste one of those .mmddyyyy files to the biblepaycore folder (the main one). Rename it from wallet.dat.ddmmyyyy to wallet.dat. Hopefully that will break the deadlock.
