Help! Long-time Vegas user here. About a month ago my Vegas 13 wouldn't open, instead a little pop-up screen appears wanting me to purchase VP16 which I had tried about a year ago. So far I've done everything to delete all traces of Vegas in the registry, program files, etc. and even installed the latest build (545) but it just never opens and keeps sending me to the VP purchase page. I even tried installing the Vegas Movie Studio but it hangs on "loading plug-ins". Next I tried to find actual Vegas Pro support on the Magix site but they don't seem to offer ANY direct support for Vegas Pro. FYI - I visited the sites below and tried to do as suggested but no go. Any ideas? Looks like my only option at this point is a whole reinstall of windows 10 and about 50 some programs, plug-ins, etc, not what I want at all. Everything else seems to work fine on my up-to-date Windows 10 (from Windows 8) desktop.
