Import GP transport package

Hi,

I am trying to import the GP .sda file which was successfully imported during the first import.

Somehow the files got corrupted. so i deleted the GP folder from design time .. undeployed and deployed again via SDM

but when i try to release the GP content under Administration->Tranposrt->Manager imported Objects

it shows me only empty folders with the following message -->

"Not all development objects that are not yet released were are added to list: 23 more objects exist"

Please help!

Veena.
