No, it helps to know if there is a patch, either here or on IRC.
If vgclient.exe is updated, ISXVG *must* be updated. It would not work without an update, so any "bypass" option would be worthless. If you compare the current client with the one that matches the ISXVG from 9/11, you'll see that it is about 4 KB different in size. That would be more than enough to crash you instantly.
By the way, I'm on Pacific Time. So, any time there is a patch I typically cannot work on it until the later evening when I get home on that particular day.
