Top Won't Open

[samg1965]

2002 Boxster....

Opened yesterday, won't open today. When I unlatch the top, the two windows drop, but when I push the button to open, nothing happens. One observation.... When the parking brake is engaged, the dash light doesn't come on (although it lights with the others upon startup). Last week I returned home after being away for a few months and my battery was dead for an extended period. There have been some "buggy" things happening such as the oil light being on when I wasn't low, the stereo not powering up, etc.... I don't know if the parking brake may be another 'buggy" programming issue, perhaps a sensor somewhere, or whether or not this is the cause of the top not opening. It's been working fine up until today.
