I recently had a problem with the market and noticed a lot of people had the same issue. When getting a new app from the market the app will either say "Starting Download" and nothing happens or the app downloads but doesn't install. I found a few threads on this problem but no fixes. so here's what i did to fix it. I recently rooted my phone and renamed some of the bloatware apps to get rid of them. (.apk to .bak) i don't use gtalk so i decided to do the same with Talk.apk and gtalkservice.apk. i also did the same with DLNA.apk (not sure if this has anything to do with it but i put it back and it works) so if you're having trouble with the market apps make sure you have Talk.apk and gtalkservice.apk on and running in the background. hope this helps anybody!
