LoadLibrary failed with error 87: The parameter is incorrect

Hey guys,
I can no longer run DAZ Studio, I put in a help desk request the other day but not had an answer yet.
I get a popup error message that comes up saying "LoadLibrary failed with error 87: The parameter is incorrect" eveytime I try to run DAZ.
Used to work I'm not sure why it's no longer working.
I've tried reinstalling but no difference,
Any ideas?
Cheers
Del
