Downloaded this but you have to pay to get a key to open it has anyone done this and are you satisfied?

It would help if you would tell us what program it is that you downloaded.

The program is called Tile It. It's a graphic file print program that accepts a number of input options and tile prints the picture or, in our case, plans onto normal sized paper. It's got a clever method of selecting the scaling factor. It's only weakness is that it won't "remember" the scale factor from one file to the next so it's hard to get mulitple pages to come out consistent. It's a cheap alternative to getting a whole bunch of programs to so the job.
