Getting “Internal error” when accessing Acronis One-Click Backup

Hello,
I just bought and loaded an upgrade from Acronis True Image 11 to Acronis True Image Home 2010.
The upgrade process went on smoothly, and I can access the main program.
However, when I try to use the Acronis One-Click Backup icon, I receive the following internal error message:
Internal Error – Please contact Acronis support team for information on how to resolve this issue.
The complete description of the issue is:
(0x0)
Tag = 0x0.
I Have enjoyed using these products and hope to do so in the future.
So what step should I take to solve this problem?
Need your help.
Thanks.
