I must apologize for the issues you are having. Not making excuses, but we have had the "perfect storm" internally with some items and its been interesting to say the least. I promise, we are working on it literally around the clock to get this resolved. i was hoping I could get the steps that you are following to make this fail, from start to finish so I can replicate the issue here. As I type this, I am importing the entire 9Gig catalog to see where the issues may still be appearing.  Could I get you to do this, which will clear your CRL cache of certificates? You will need to close all applications before running the command.  from a command prompt run as administrator: certutil -urlcache * delete Then try the import/export again. I did try importing that single file as part of a bundle, it imported correctly and exported to SUU directory correctly. I did this on my system and on a newly installed system and it worked flawlessly. 
Forum Members -  I am getting an error with Dell Repository Manager 1.4.104 when trying to create my first repository.  I choose Create -> New, give the repository a name, and then choose Dell Online Repository (ftp.dell.com) as my source repository.  When I click next I get the following error: "Error loading source repository.  Digital signature verification error for 'ftp://ftp.dell.com/catalog/Catalog.cab'"  Any ideas as to what may be causing this error?  I can access the FTP site from the computer that I am running the repository manager on, so I am pretty sure that it is not a problem with the network.  Thanks, James
