DS Visualiser 2.5 problem, wont open molecule files!

Hi,

I have just recently installed DS Visualizer 2.5 on my linux machine.
I was using the old DS Visualizer 2.0 previous to that.

The problem is when I try to open sdf, mol2 files etc in the 2.5 version i get an error message, please see attachment of a screen shot.

It fails to load ppchemapi library.

Can anyone please help?

Regards

Donna
