you should have a number of options on the start-up screen - one should be something like "try now" - then it'll say you have 30 days remaining or somwthing along those lines - been a long time since I've seen that screen - but it is the full version of the programme, means that if you wanna use it after the 30 days you can simply submit your details off to Autodesk - they'll then give you the codes to unlock it FOREVER! :bounce:
