Gmod won't start.

I had my gmod working for a long time, until today, today i put a command in startup commands in additon to another it looked like this: -32bit -window. I tried to start gmod and it did not work so i changed the command back to -32bit as always, but it still wont start, it just says launching and nothing comes up :L help anyone?

What if you try removing the -32bit

Getting the same problem, only this is without having any launch options at all. Steam tells me its launching, and then it doesn’t do anything.
