Once again, HEM2 has left me completely baffled.
I found a site, pelo poker, which allows me to build fictional hands and then export them in HH format which I can then import to HEM2.
This was working great, I imported 10 hands or so, no problem at all. Then a few days back I was importing further hands and it suddenly stopped working. 2 minutes prior I had successfully imported a built hand, and now 2 minutes later it didn't work. What's more, it refuses to re-import any of the hands I'd exported from pelo-poker previously, which leads me to suspect it's something to do with HEM2 rather than pelo-poker. (It acts like it has imported the files but then says 0 hands, 0 duplicates)
I've changed nothing whatsoever. I even tried clicking the "restore defaults" option in the manual HH import section, but to no avail. As far as I can see HEM2 has just randomly stopped importing my built hands for no reason whatsoever.
