>In case anyone is interested - this is resolved. I had a corrupted GS dll related to the GS fll and this affected the loading of the fll. Reinstalled GS and all is working.

Jos,

Are yoi saying that corrupted FLL loaded fine under VFP8RTM but not under VFP8SP1 or it's just coincidence that it got corrupted at the same time when SP1 was installed?
