PMEBLib.dll missing

After lenovo update I get the following message:
The program can't start because PMEBLib.dll is missing from your computer. Try reinstalling the program to fix this problem.

I have a Lenovo 3000 N200 notebook with the english download of the 32-bit Windows 7 Beta running with german country settings.

Fingerprint scanner AES 2501 A still not working.
