Upgrade from T-Seps 3.0 to T-Seps 3.5.5
In June of 2014, Adobe made major changes to how plug-ins work in their new Photoshop CC 2014. This meant a total re-write of the interface for Photoshop and a lot of work with other issues and other issues to overcome things they broke or changed. In June of 2016 they did the same thing. T-Seps 3.5.5 only works in Photoshop CC, CC 2014, CC 2015 and CC 2015.5. T-Seps 3.0 and 3.5.5 can co-exist on the same computer because Adobe will let you have multiple versions of their Cloud software on the same computer. T-Seps 3.5.5 will require a new unlock.
