I just logged into SOLAR, but for some reason UNDERGRAD REGISTRATION/COURSE SELECTION for the SEP 2011 SESSION is unavailable.
SOLAR is supposed to be available starting 8:30am on August 10th.

I completed my payment agreement in early July.

Does anyone know why? Thanks. : )

Ahhh, I found the answer over at the Academics forum. Didn't think it'd be over there;; I apologize about that!

Is there an option for deleting this thread?

It's like that for everyone, don't worry.

There's already two threads on this..you should read up on those. Basically people have been saying that either the server is down (unlikely) or most probably they screwed up on the timings on when to open up SOLAR.

check out the other threads, they're about the exact same topic
