Your implied accusation is an inexusable as a vius. That being said, unless you donated some large amount of money, for instance, larger than I (which I know you didn't), then I wouldn't be complaining. Not having access to this incredibly usefull FREE tool for 48 hours will not ruin your life. Furthermore, as part of ANY software development cycle worth it's beans, you will find a way to kill older copies of software to prevent a variety of items, from people mis-interpreting the software because they have a bad beta copy, to simply making the user experiance better, to comabatting piracy. Please, show some respect to someone who hasn't charged anything, nor made much money off of this great product.
