GMod error - Bad Module

What’s this mean ; how do I fix it?

Please excuse the file name, I was very stressed and excruciatingly angry when my game crashed.

[sp]i was bored[/sp]

These could be the reasons:
[li]Addon interfirance[/li][li]You :yarr:'ed Gmod[/li][li]dxlevel is not set to -81 or -80[/li][li]Your steam is :yarr:'ed[/li][li]Garry’s mod was not installed properly[/li][li]You have a LUA virus[/li][/ul]
And calm down its not the end of Garry’s mod. Hurr

I own GMod legally, hurf. I guess the update broke LuaMenu FOUR WEEKS AGO.
