Gmod can't load files from /lua/includes/modules

Thanks in advance to anyone that can help me…

I have recently re-installed Windows7, I didn’t have the problem before…

Gmod is unable to load lua files and modules from /lua

error loading module 'extras' from file 'c:\program files (x86)\steam\steamapps\USERNAME\garrysmod\garrysmod\lua\includes\modules\gmcl_extras.dll':
The specified module could not be found.

But as you can clearly see in the below pic, the module is there.
Same happens for the other modules.

Also, is this normal?


bump again I really need this to work

Was it that easy this whole time? :s
