Trial version expired after three days?

 From:  Tiger1
same problem here: trial version expired after about 3 hours. I'm running XP on an old AMD 1.7
Will probably buy for the mesher anyway but it would be nice to test it a while longer. Mesher seems to be a lot better than those built into Rhino - and much better than Polytrans. I have had a couple of problems though with some rhino files crashing MOI. Also - is there any sort of layer support? I'm having to break Rhino models down into 1 layer per rhino file and export via MOI as obj in order to keep layers separate for Cinema 4d. Is there a better way to do this?
Thanks, Michael
