DLL sqlceme30.dll error

When trying to run the samples, everything works ok until I hit the Synchronize button. Then I get the following error:

Unable to find an entry point named 'ME_SetTransactionFlag' in DLL 'sqlceme30.dll'.

I am running the samples on a Windows XP SP2, with System.Data.SqlServerCe.dll version 3.5.0.0.

Any idea what the problem can be?

Thanks .
