Unzipping Files Problem!!

[superturtlegamer411]

Every time I try to get into tekkit lite (or any other mod pack besides Tekkit, Volts and Vanilla) it tells me that it has a problem with unzipping a file!

The file name is:

lwjgl-natives-osx-2.4.2.zip

PLEASE HELP ME!!!

Can you provide the full error?

So whenever I try to launch Tekkit Lite from the Technic Launcher, this window pops up:

Error unzipping file from the following pack: Tekkit Lite

Error unzipping file: /users/smalle/library/application support/technic/cashe/lwjigl-natives-osx-2.4.2.zip

Please consult the mod pack author, or try to run the pack again.

Ok so I just tried to go into Hexxit and Tekkit Classic, and the same error popped up for both of them.
