Forgive my ignorance here but I have no clue what I need to do to get my HEM2 working. I used to play a decent amount back in 2012, but then I don't think I played online in the last 7 years or so. I tried to open HEM2 and got a bunch of errors, saying it couldn't validate the license and such. I haven't used a different computer than the one I'm on.
How should I proceed?
