just recieved "DLC corrupted" message, help needed

 So i just decided to make a new playthrough in ME2 with an old career and recieved the "All DLC corrupted" error message. So i deleted every peice of DLC , but now i'v lost my Collector Armour and weapons, Blood Dragon Armour and Zaeed. 

Is there something obvious i'm missing?

I dont know what to do...i'v tried re-registering my Collectors edition but it just says it's already rergistered, same for my Blood Dragon armour.

I would be massively thankful for some help, i'm desperate!

I'm jonesin' for some ME2

Nevermind, i'v sorted it out.

Cheers anyway.
