I have a clean install of d20pro 7.2. I am using Mac OS X 10.13.3. I have exported/ imported maps from the previous version. I have copied and pasted the campaign folder from the previous version. So, I was following the step-by-step instructions so kindly posted by Vanith (thank you). When I attempt to save the feature/trait/spell thing, I receive the spinning beach ball of death. Regardless of the length of time I wait, the program just hangs. Eventually, I have to forcequit D20Pro. I do not know how to overcome this issue. I am frustrated. I would really like the old system of applying effects at least until this process is stable. Right now, I am finding it very difficult to prepare for Friday's game. I fear I will end up using the program as merely a digital map. Please some one save me.
