Unrecoverable Error in Microsoft UAG

We are using Microsoft Forefront Unified Access Gateway (UAG) in our company. Recently, we have installed the new version of UAG in our newly installed Windows 7, but got the following error messages: “The configuration cannot be located from Force front TMG storage” and “An unrecoverable error has occurred. The application will close.” What can I do to fix this? Help me to solve these problems.
Thanks.
