All your future possibilities are stuff unless you fork out less than you spend on drinks on your average night out.
This is how ALL time cripped shareware works.
If you could simply uninstall it then install it again to make it start again from scratch then what would prevent people from just uninstalling it each time their trial ran out then re-installing it??
Nothing!
Try any time cripped software and you'll see this is how it works. This includes BIG name brands and software - try a demo of Macromedia Dreamweaver for instance - same exact method.
It can be a pain if you do install it, try it for a day then forget about it, I've done this before with some software and when I wanted to try it out in depth couldn't but it's my own fault for not testing it when I had the chance.
The developers were nice enough to give me a trial period to see if I liked it in the first place.
If only car companies would let me drive around in cars for a couple of weeks before I bought it to see if I liked it I'd be happy
