HTC Droid Eris :: App Download Failed

This problem first started after installing Lock bot, ATK and Alevel. Rebooted my phone and was greeted with an X in my signal bar and all home apps and google/android apps FC. I tried to reboot and pull battery even though the battery pull from my understanding has no effect. I've seen other threads say to do a hard reset but I didn't have a back up of my phone. I uninstall the 3 apps listed and the phone booted up fine.The next day I downloaded lock bot and level whith a reboot after each and no problems. I went back to tk because i like the 1x4 task bar it has and all was well.(No i'm not blaming ATK because too many people use it successfully) Yesterday I downloaded Safe neighborhood(My creepy neighbor looks out his window and watches the kids way too much), OS Monitor after uninstalling TK, and the Swype app I found on a thread here. As soon as I rebooted I received that X again. Uninstalled the last three apps and O.K.. I have re-installed OS Monitor and swype and phone reboots fine. I didn't download safe neighborhood again because my neighbor may be a perv but now I know he's not a convicted perv. The thing I'm noticing now is that when trying to use the market the downloads take several minutes to load or don't load at all.
