I've been using ZipItFast and just recently downloaded the Pro version. I might add that the first time I opend the zip file not only didn't the files go where they should have in the runtime but the entire file disappeared from the zip. However, this is the first time this has happened. 

The product is 'Seren' and I've seen renders posted using her, the artist who created her was kind enought to gift her to me and a few others and no one else seems to have had this problem....just me sigh

I haven't downloaded anything since so is it possible the program I use has corrupted somehow?
