Backed up apps

[justcop]

I have a installed an image which includes apps2sd. Before I installed it I used the function in the recovery mode to backup apps to sd.

I was pleasantly surprised to see that all my apps in the backup folder where automatically loaded on to the new firmware which was otherwise clean.

I then removed everything on my sd to the desktop and reformatted, when I moved everything back on and restarted all the apps were missing.

How do I get them to come back?!
