So, up until recently I've managed to launch this without any errors, although...now it appears I've encountered this error upon clicking start in the launcher client, I haven't re-adjusted anything or modified files.
I've attempted to run as administrator/ in compatibility mode. I've also uninstalled Boutcheetah and re-downloaded the client itself again and reinstalled, I've read numerous threads about how it'll be fixed if you redownload the client, but I am yet to succeed.
Here is the error that occurs upon starting up:
Debug Assertion Failed!
program: C:\Zylon Gaming\BoutCheetah\bout.dat
File: fseek.c
Line: 101
Expression: str != NULL
For information on how your program can cause an assertion
failure, see the visual C+ + documentation on asserts.
