I had been running my student version of R14 for several years on my XP pc without a hitch. My operating system got corrupted and I had the hard drive wiped and a new os installed, however, my R14 will NOT accept the authorization code to validate my program... I only have a few days left. Any ideas on how to remedy this problem? AutoDesk Business Ctr gave me my code, an hr+ of assistance, and the headsup to try this discussion group.
