File repository server error when importing universe

Hi All,

When i am trying to import any universe in the repository i am getting this error message:

"File Repository Server Error : File frs://XXXX/XX/XXX/abc.unv not found on File Repository Server".

When i open the CMS, i can see the universe in the particular folder.

I have rebooted the servers, and restarted the servers as well. First time when i rebooted i could import one universe. But suddenly again i can't import any of the unvierse and problem is still there.

Help Please.
