My old computer crashed. Do I upgrade or buy new programs?

Have you tried going into your account : http://www.mtu.com/support/customer-...t.htm#RegCodes
Providing you know the email address you used at the time of creating it and know the password you used for the account you will find all your registration details there and can also change details if you have a new email account for getting mail back, but it won't change your original registration email.

If none of the above work for you try the ordinary help ticket not the emergency one here: http://www.mtu.com/support/customer-...htm#HelpTicket

I don't think you need any of your registration details using that one but of course you will need to give them something to identify you.

Other than that I think you would have to buy the new software.
And remember in future to keep printed copy of your details for safe keeping.
