I recently purchased a computer that I could run SH5 on. The problem is that I had attempted to install it on my old system and it wasn't compatible. I uninstalled and when I went to install it on the new system it wouldn't let me do it. It said the entry code was linked to the old log-in name. I had forgotten it since then. Therein lies the problem, how do I, or can I reset it to run on this machine?
