Hey Guys!

I've been having an issue the whole day, everytime I start up Gmod, it would always crash not even letting me check the menu or anything, in the past weeks I've been playing, it was working perfectly, now it won't even start up and its really starting to frustrate me. I tried re-installing it, restarting my PC.

So, can I have any assistance to help me fix my Gmod problem?
