I'm just having hassle actually getting the Snap 5 registration key, their site is an absolute mess. Can't get past step 2, well can't even get to step 2 whatever the complete basic user profile is, even more so where the heck is the basic profile that requires completion.
I have fired them off an angry email as to install Snap 5 I had to uninstall Snap as it installs in a different location, so I couldn't save my customisations and then I couldn't bl**dy register it, not a happy bear.
If I remember rightly I had hassle getting Snap 3 registered also.
