You really need to provide more information. "mIRC crashes and it didn't used to" is really not enough to go on. It's more of a diagnosis than a debugging, but you should disable all scripts and DLLs as mentioned. In fact, installing a fresh copy of mIRC in another directory (copy an empty mirc.ini into the directory to have mIRC run out of that dir instead of your AppData directory) will see if mIRC is crashing or if it is a script. Then, load each script back individually until mIRC starts crashing again. It may be a slow process, but that's the best way to do it.
All the .mrc are related, no way i can enable one and disable the others, now i'm pretty sure it's a DLL compatibility problem, where may i ask for updated versions?
