android.process.media has stopped unexpectedly?

I downloaded a few apps, deleted some I didnt like. After i messed around with some of them, playing them, when I try to download more it's giving me the message "The process android.process.media has stopped unexpectedly. Please try again."

I don't know why this is happening; i got it today.

 

I even tried to download one of the previous apps I deleted, and guess what... Won't download now.

 

People are reporting Market problems, usually late at night. It is suspected that Google is getting ready for the release of 2.3. See this article for example...
