Personally I do not see the issuue with copy protection. If it is good enough for Microsoft and other software developers, then why not Virtual Acorn. I have a copy of VA, and have and two unlock codes from VA. One when I first installed it, another when I changed the PC I was using it one. VA have always been quick to respond to any enquiries with regards to the licensing unloc codes.
If Richard wants a refund, all he needs to do is uninstall it and right a letter to VA stating that any copies have been removed/destroyed. Talk about a 'storm in a teacup!'.
