1. Delete the current program installed (H2V)
2. Re-insert the disk
3. Re-download

if this doesnt work try this:
1. the disk might be scratched
2. Your diskdrive has gone bad*
3. Run a defrag on your computer
4. Run a system scan for virus or cookies**

* if you have a warranty get a new disk drive, if not go out and buy a new one.
** enough cookies can serverly slow down your computer performance which might take out the needed space for the program to work.

If this doesn't work..... :/
