Gmod only loads 48 out of my 475 addons

I haven’t downloaded an addon in days, and haven’t had problems until today. For some reason Gmod thinks that I only have 48 addons. I have checked my subscribed addons, and my files and everything is there. I don’t know what is going on. I’ve tried deleting all of my addons, and it didn’t work, because it just loads up 48 random addons. I am in the middle of reinstalling. If that works I will close this thread, but until then, I need suggestions on how to fix this.

Did you even bother to search? Or even look at the top threads in the board?

Usually the problems I have are isolated. Anyway, it would be great to have people posting on multiple threads to increase the awareness.
