Can I use PCMScandinavia's DB after installing this patch?

yes

yes

Thanks

cool

You can use it, but it's not compatible, meaning that not all improvements from the patch will work if you use that DB.

from the moment i install this patch i suddenly have to give some kind of disc key...
before the patch i didn't have to
can somebody help???

the file is corrupt, it should have a 317mb, not 91.4mb
