As per my knowledge using free version will not cause you any problem if you are creating a report for your personal laptop/desktop. However If you would like to import/export those report it wont work. Free Edition is only for the creating report for your personal use, not for distribution. That's the only restriction in QlikView free version. Remaining you can enjoy all the features, what a personal edition provides. If this doesn't answer your question, please come back with the problem what exactly you are facing.
