I just installed the X4 trial, and it crashed while opening. When I went back and reloaded it, I was told the trial was over and I’d have to buy it. That was the fastest 30 days I’ve ever had in my life!
Wow, I’m really surprised that it’s taken more than five days for someone to answer a question on this forum. that doesn’t bode well for the kind of service I would expect from the newest version of EndNote.
