Welcome to WebmasterWorld, helder.

This means there is some problem with the DLL or the registry settings for the DLL.

Easiest thing is to uninstall the DLL and then reinstall it.

If that doesn't work, then manually register the DLL and all DLLs that this DLL relies on by hand. You do that by creating a Command window and changing to the directory where the DLL is installed. Then do:

regsvr32 dllname.dll

where dllname is replaced by the name of the DLL.

If that doesn't work, you will need to contact whoever produced that DLL in the first place, as there is some bug within the internals of the DLL.

If you have questions about this process, come back and post again.
