Player cannot download files
I recently purchased the Starfinder Ruleset and I'm trying to get everything set up.
I'm running an Ultimate license of FG, and everything is working fine with e.g. the PFRPG ruleset.
The current person I'm testing with has an Ultimate license of his own, but doesn't own the Starfinder Ruleset.
Shouldn't he be able to join a Starfinder game when I host it?
Whenever he connects, his client starts downloading files, and simply stops at 20% with no error message. After a few minutes his client just exits into the launcher.
Since there are no errors shown anywhere it is damn difficult to troubleshoot this problem, therefore I'm turning to these forums for help.
Does anyone have an idea what could be causing this behaviour?
