Hi!
Does the old trick of moving time backwards work with demo versions that experies after 30 days?
Im interested in a prigram that still hasnt been cracked and would like to run a demo version 30 day trial (all features available).
Anyone has any experience before I try and start conting time

install the software with total uninstaller, and the look what the program has written in the registry (check the differences). Clean the most probable key connected with the sw, or uninstall wit total unistaller and reinstall again
