Serial number expired?

System

Hi,

I am on Windows 2000, using mediabin 4.6.1.

After installing TS 6.7.2 with LiveSite/SitePublisher 3.1.0, I am getting this in the MPB.log:

06/01/09 11:54:39 ******************** MediaBin Server Version MediaBin 4.6.1 Build 7 starting. ********************
06/01/09 11:54:40 Serial number expired.

Anybody know if there are any incompatibilities with TS6.7.2/LS3.1 with Mediabin 4.6.1? Thanks,
