1st - delete the "FlorensiaEN.exe" in your "Bin" folder.
2nd - delete the "ClientFileInfo.bin" and "ClientFileInfo_head.bin" in your "Settings" folder.
3rd - start the "launcher.exe" and update your client.
4th - close your florensia client
And last but not least - start the "Bypass2.exe". After this it should work.
If your using the hack for the first time, then the first step isn't necessary.
Btw.. after every update you'll need to do this again.
