Question:
Are you watching the clips as the rest of the card downloads,
but after they Finish downloading, they are no longer watchable and then you have to download again?
an error right at the end of the download and you have to re-download again?
If answer is NO try this..
If Yes, Leave a reply...
Quit VG, and the downloader ( use taskmanager if you have to)
I would open your data folder and make a backup of these two files.
models.lst
models.vghd
after you have a saved copy
Delete both of those files from the data folder.
restart VG
let it rebuild
Did that Fix it?
