Installing themes…WPMU Themes..all give me error

I apparently have a problem that I’m haven’t been aware of at all. I’ve been working on settng up a WPMU site. The themes and plugins I’ve been using have been working fine in testing. Just basic themes and plugins. It doesn’t appear to be a specific theme other than WPMU themes.

Today I tried installing the WPMU Themes to test them out and none of them will install. I get a variety of errors. I checked my permissions and they are all set properly. (755) I’ve installed the themes manually. The other themes installed work just fine but I really want to use a couple of the WPMU themes.

Something must be wrong in a general sense because I can’t get any of the WPMU plugins to work either. I’ve installed them in the WPMU folder manually.

Anyone have any ideas on what to look for? I’m using WPMU 2.9.2

Hoping to go live this next week.
