Rs logix 5000 student version

I have finished the micrologix 1000 series course at a local college. I am now enroled in the rs logix 5000 course. When taking the micrologix course I obtained a copy of micrologix lite to use at home. I cannot afford the software from allen bradley for the rslogix 5k, it comes out of my pocket. Is there a version of the rs logix 5k that i can use at home. The trainer at school is booked solid. I only need it thru may 2010 so if it has a 120 day window before it corrupts thats fine. I tried locating a student version but to no avail, i just cannot locate one or maybe i am looking in all the wrong places. We are not using ab plc's at work yet, that my job to introduce them, that is, if i can get trained.

Thanks
