Commented Unassigned: Failed to sign package; error was: 2148204801 [242]

I keep getting the above error message every time I try to import or create a new update. I tried reloading the certificate but not having any luck. This just started either yesterday or the day before as everything was working perfectly earlier this week.
Any help with this error is greatly appreciated.
Comments: Never mind - I just realized that the Certificate expired on the 14th. If at all possible, it would be nice for that error message to change to something that actually says the Code Signing Certificate has expired instead of "2148204801". Thanks
