Android Camera not Working?

[.Chris]

I recently rooted my LG Optimus ME, also known as LG P350, and it was working perfectly fine.
After I installed some apps (I think), the camera stopped working. It came up with an error/notification:

Failure to start Preview

whenever I start up any Camera application.

I have searched on this, and I have found little information on this problem. I saw that I would have to "reflash" my phone.

If not, how would I fix this problem?

What did you install, for a start?

Well, I think I installed adFree, FasterGPS, MyBackup Pro, and Minecraft Mobile Manager, but I don't see how those applications would interfere.

I have also tried restoring a Data Backup, from MyBackup, but that didn't work. So I tried factory restore, but that did not work either.

This has happened to me before, but I restarted the phone and it fixed itself.
Maybe you could try wiping the cache/dalvik cache in recovery.

Wait, in recovery? As in Custom Recovery?

Ah, I thought I read that you were running a custom ROM for some reason. o.0
Yes, I was talking about Clockworkmod Recovery, but I don't know what to do should you not have that...

When I selected the Recovery in Clockworkmod Recovery, it just factory reseted it... D:

Selected the recovery in CWM?
In CWM, just go to wipe cache.
I don't know how CWM can make your phone factory reset unless you restored a backup from then, or wiped the data or something.
