Help Apps auto uninstalling - HELP!!!

[rqballjh]

Over the last few days I've had several app get uninstalled by what, magic?, I don't know. Frozen Bubble is even removed from my Astro backups?? When I go to the market, it shows the app in my list of downloads but doesn't say installed, it sys free, but when I look at the app in the market, it shows me the rating option like it knows I have it installed, then just has an install button. When I try to install it downloads, then when instlaling it says Installation unsuccessful, with no further info to know why.

This isn't the only app this has happened to, any ideas guys?

DroidX, 2.2, non rooted

It's still happening, other apps now, Trap, AirAttack, history eraser, all auto uninstalled, and all resided onthe SDcard. Some will let me re-install, some download then fail installation.

Any ideas guys????

It seems to have started a few days ago when I tried to d/l angry birds, that install failed and now I'm having apps dissappearing..........
