HELP! Problem starting the K800i camera !

Camera was working fine previously without any problems. Then a few days ago, when I tried to use the camera, I got the message "Another application is running. Close it and then start the camera." even though there no applications were running.

I've tried everything I could think of (updating firmware with SEUS, switching off the hand phone, reinserting the battery etc.) but to no avail. What's happening?

I've only used the hand phone camera a few times. Never dropped it..in perfect working condition..yet I'm getting this problem...:(

Firmware version is CID53

cid 53 not good sounds like a hard were fault if reflashing it with seus hasnt worked

In that case, is it possible to repair it myself? Thanks!
