C:\ProgramData\com.aspexsoftware.Silhouette_Studio.8 does contain an index file, but for some reason the program isnt picking up the index from the program data file, I get Cannot read in the index file. I have no idea why, and when I copy and paste the path into the address box there is no way to get it to "work/Start" the process. in the users C:\Users\mum\AppData\Roaming\com.aspexsoftware.Silhouette_Studio there is no idex file, sorry
as to the file you provided downloading and converting yes it does, I think what I was trying to do was convert the files direct from my program data folder as opposed to saving them from within studio first, then converting them, sorry forgot about studios inability to share!
