Vegas Pro 14 worked without a problem on the same computer but all I can think is I may have somehow erased it without deactivating it and now "HandlePIchanges" comes on and freezes to a point where I have to shut off the computer since I cannot get out of it. Did reinstall and got "activated" message but am blocked as soon as Vegas comes on. Will greatly appreciate if someone can let me know how to "Handle PI changes" issue resolved so I can work on my editing projects again. Thank you in advance!
