Default Apps will not install/update anymore

I'm trying to install and update apps from appbrain/market and they will not install or even update. It says starting download and it just sits there. This started yesterday morning and I haven't been able to figure out why it won't download anything at all.

I'm running Fresh 0.3 and even reflashed (w/o deleting data/cache), but that dind't help either.

Any idea why this is occuring?
