Welcome to the forum.
Option 1] Hop over to PayPal and send me an obscene amount of
money! I'll come and fix it wherever you are.
Option 2] Delete the CPD file before opening the project from
the XPJ file. It will open and should be OK provided the client has
not done anything RH6 specific, like use variables. There's more
about this in the topic about Opening Projects on my site.
Are you aware that you can run both X5 and RH6 on the same
PC? You have to buy the full version of RH6, not the upgrade, but
they work quite happily together.
