Shady business tactics
The program itself is very user friendly and looks good, plus it works as intended and really well. It definitely fixed a file in the preview, but in order to save the file you have to buy a license which is $30 for a month, $40 for a year and an unlimited time license for $54 which at the time of writing is on sale. I skimmed through their site for the program and it doesn't hint anywhere that you have to buy a license in order to save your file. It only tells you after you've used the program to fix your file and try to save it. I wouldn't recommend it.
