E-trust ITM 8.1 won't download AV updates

I'm running (testing) Windows 7 (32bit)...
Having a problem updating signatures for CA's E-Trust ITM 8.1 - basically it gets just a little bit into downloading updates, then it closes.  It gets to the same point every time (it apparently finishes downloading "masteritm_81.xml") then closes (see screenshot).

I've tried downloading from both the default location (which works for all our other machines running WinXP when I initially install the software), and from our server which all machines download from regularly.  Neither location is successful.

Also note that no firewall software is running that would block it.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
