Mod doesnt load

Don't think the error is anything to do with my code or anything as it happens with all mods, optifine, reis minimap... All mods are of the right version for the forge I am using (when running mc through eclipse, the mod loads fine and I can see in the bottom left that the forge version is the same as the one i'm trying to use with my actual mc). Yes I've tried re-installing, doesn't fix.

Here's a snip of the logs where the error occurs, would like to know whats up if anyone can spot the issue:

	Zip file modid-1.0.0.jar failed to read properly, it will be ignored
