Can someone help me with an Audio problem I'm having with Adobe Premiere Pro? - adobe premiere pro 1.5 key generator

I have Adobe Premiere Pro v. 1.5. I have a few films for my film class, and export to DVD 5.1 surround. The problem I have is the 5.1 Dolby Digital Encoder (SurCode of Minnetonka Audio) was obviously a trial version and now can not export audio mixing in surround sound for me. Does anyone know of another was 5.1 encoder also be used, or a way to solve this problem, the study? I am a student, so you do not pay for the key program of $ 250. Please help! I will send a film on the festival circuit, but I have my audio work. Thank you.
