I hate to say it, but I think there is still an issue. Maybe just with the trial version?
I'm still seeing it load to 100% then crash. This is for a completely clean install of version 1.5.17 on Windows 8 (a Surface Pro).
The spine.log looks a bit different though, it's just 6 lines long and ends after the line 'Spine 1.5.17 trial, LWJGL'. There's also a huge log file from the JRE, showing an access violation.
It's still working on my desktop though, but having said that, the earlier problem build worked there too. I'd already had an earlier build running on the desktop, so there are valid settings and a valid .spine for it to load, would that make a difference?
Let me know if you need more info, or if you think I should start a new bug topic.
