Do I have to renew at some future time?
The default license period for ErrorTeck is 1 year. After that period, if you wish to continue using the program, you will have to renew the license. The developers of the software have an offer to extend your license for 3 years for $9.95 additional cost if you are willing to purchase a new copy of ErrorTeck. The product can be downloaded from the developer's official page.
