[Plugin: NextGEN Gallery] options and upload blank after upgrade

I recently upgraded both wordpress and nextgen gallery at the same time to the newest versions 2.7 and 1.0.1 respectively.
everything was working just fine before i did this. after the upgrade i found that both the options page and the manage gallery page no longer worked. the links were there for upload, effects, etc. but they no longer did anything at all.
I saw that there was this white screen bug that people were talking about but i wasn’t sure if it was the same thing and i saw no solutions. I figured maybe it was a flash error.
I tried in both Safari and Camino.
tried deactivating all other plugins
tried reinstalling both nextgen and wordpress
tried changing permissions (everything is 755. that has been working in the past)
eventually I reverted back to older versions of WP and Nextgen ’cause i need this to work. Older versions still work. but i would like to upgrade if this can be fixed
thanks
