Hasta La Motion!

Hi to all….I thought of learning silhouette for rotoscoping..I had downloaded the software a month ago and had accidentally set it into trial activation..But i never used it back then as i was concentrating on Fusion for some time…Now when try to use the trial version with all features it says trial version expired…So i deleted it and re-installed it again, but again the same error…Can anyone help me on this because i really wanna use all the features..Is there any way to make silhouette work with all the features again for 15 days….

PS.. In demo mode no saves…WTH…roto needs saves..Also my area is prone to power shutdowns…LOL..
