Question: I purchased a downloadable full working version and now all of the sudden it's not working anymore and it asks me to relicense but I can't - what should I do? Answer: Most likely something happened which caused your software to become 'unlicensed'. This could happen for many reasons including: 1. You had a system crash and had to reinstall the software 2. Somehow the license file was deleted 3. There was a software conflict with an existing application and the software needs to be reinstalled To solve this problem, please contact Customer_service@ntius.com or (949)-421-0720 x100 and have as much as much of the listed information below as possible, on-hand.
