Hi Alex!
Nope it has nothing to do with the NAS/network drives.
I have the error if I export to jpeg but not TIFF... So I think they are related.
I dident have this problem with version 1.4.3 witch was ther prevously one we used, gonna try to reinstall the old 1.4.3 version an see if its still a problem.
