Hidden files deleted => OS X sluggisch unfunctioning

[Jasinn]

Hey guys,

I accidently made a dumb mistake by deleting some hidden files which consequently made my OS X very slow and not functioning (cant open any of MS Excel, Word .. neither can i surf the internet).

Does anybody know how to make my OS X work properply again without losing all my school files?

Many thanks!

reinstall OSX would be a good start, or if you have a time machine backup, restore from a point before you deleted those files.

Backup your data and re-install OS X.
