Hello,
I had similar issue that it failed to create/activate the license.
What solved the issue for me is that I changed my forum password from what I used on the main massive site (https://www.massivesoftware.com/).

After changing the password it works perfectly. I hope it helps :D

Thanks for the stack trace goldfarb. I'm pretty sure we've figured out the problem now. There should be new builds in the next day or so, once we've finished testing them.

Great - looking forward to it.

Could I make a request regarding the downloads?
on the Downloads page could the versions be added to the link?
so for Linux massive101_version###.tgz etc

I have also encountered the exact same issue as goldfarb above. Rocky Linux 8.10

+1 for this as well! Then I can be sure I'm downloading and deploying a new version!

Massive 101 9.3.2 is now available. We also modified the download page so that the version number is clear and that the downloaded filenames include the version number.

Here's what's fixed in 9.3.2:

Bug 9419 Massive 101 linux segfault
Bug 9420 Crash when running a scene with terrain visible to agents
Bug 9421 Bullet instability on windows
Bug 9422 Occasional crash when loading mas file on windows
Bug 9423 Agents not visible after loading a setup
Bug 9424 loading a mas file with agents that use collisions after placing agents crashes

9420 is the plod.mas crash. It turned out the we somehow ended up with the wrong pthread library in windows.

9421 This one caused ants.mas agents to explode. It was also due to an external library. It seems that by default, visual studio compiles with floating point accuracy set to "wrong answers only". So we rebuilt the Bullet library with floating point accuracy set to "precise".

9423 is not so much a bug as a potentially confusing consequence. When loading a mas file after instancing agents with geometry, if the new agents don't have any geometry then they won't be visible. Simple fix was to just reset the view options when loading a new scene.

9424 We found that loading a scene with agents that use the "collide" input channel, after running a scene that doesn't caused a crash. Strangely, loading the scene fresh didn't crash.

Hopefully this gets us past the initial release teething problems.
If there are any more issues please post so that we can fix them.

From the logs it appears that the password check is failing. So either the wrong password is being entered or it contains characters that are confusing the authentication process.

changed my password to something much simpler - was able to start the program on Windows - no issues.
I'll try again on Linux when I'm next able.

thanks
