MDS Error: 0 : Evaluation period has expired.

Hi,

I had a SQL Server 2008 R2 Enterprise installed now I downloaded the SQL Server 2012 trial to try the new features.

I uninstalled the 2008 R2 version and installed the 2012 trial edition.

There was no problem, but the Master Data Services web application fails, it says that the Evoluation period has expired. 

I tried to find some information about this issue, I found the following forum without solution:

I set the web.config to log to file, now I have the following log entries in the log file:

MDS Error: 0 : Service started successfully,  Assembly version: 11.0.0.0, file version: 11.0.2100.60 ((SQL11_RTM).120210-1917 )

...

MDS Stop: 2 : Service.InitializeExpirationStatus

I checked the dll file in C:\Program Files\Microsoft SQL Server\110\Shared\sqlboot.dll still exists...

Have you got any idea how to solve this problem?

Thanks in advance!
