Market Not Working?

[dirtleg]

I accidentally deleted my Amazon mp3 downloader today...no big deal I thought. Immediately after I can't download from market. It starts downloading and then force closes before it installs the app. I reinstalled amazon mp3 but still can't download from the market...anyone have this problem and a solution?

EDIT: Even redoing the apk didn't work. I ended up doing a restore..(thank you nandroid!!) Everything back to normal...
Note to self and others...deleting amazon mp3 MAY cause some issues.
