F1 2013 Checking content crash and reboot [steam]

[taiN]

Hi lads,

My F1 was working normally, then I decided to put a realistic crash dmg mod in it (just one xml file).. and when I started the game it crashed at the beginning where after cinematics you press enter and there is checking downloadable content thing... it just crash and start itself again, 
1. I removed the mod and put original files back
2. Verified integrity of game cache
3. turned off steam cloud
4. Set all admin and user permissions for everything connected with steam 

and nothing worked so far... the crash dump file says it's 0xC0000005 error "The thread tried to read from or write to a virtual address for which it does not have the appropriate access." 

I really don't understand because everything worked properly before, if anyone would have some advice for me I would be really grateful.
Thank you for your time and have a great day!
