My friend's seeking for help

[STyL4]

My friend on xfire said that he can't connect to any SA:MP server because even the "Loading" bar doesn't want to open.. All he gets is the black window and the "buffering" piece of mouse part.

He's using Windows 7, and this is the message he gets:
"A running programe isn't compatible with certain visual elements of Windows"

I asked him if he's using any mods and he said he's only using hud.txd and font.txd. He could play with them yesterday though.

Thanks
