I purchased this software with the intent of increasing my Bootcamp partition size, and have not been able to get it to work so far. I have tried it 3 times. The first time, it got stuck on "Checking Bootcamp partition". Since then, I have not been able to get past "Checking Mac OS X partition". It is quite frustrating that a $20 program is incapable of performing as advertised. If anybody knows a solution to this problem, please let me know... otherwise I may have to seek a refund.
