Testversion

If you don't need the software any more, you have to delete it from your computer.  Otherwise it will just stay there forever.

Not sure what you mean by "automatic".   the 30 day trial is a 100% fully functional version.   You don't "get billed" automatically at the end of 30 days-- it's totally up to you.  Many users simply buy it after a week or so.   I alway recommend that a user wait till like day 28 before they pruchase:  It might go on sale. 

It's on sale in the U.S. now:   No, you can't live in Germany and get it on sale fro a U.S. website.
