Dunno, I'm not related to Doll Divine in any way. The gal that runs the place asked if she could host my games and I said yes and she handled all the setup, I just sent her the game files. Best to find a contact on her website and ask her.
I ain't a tech at all, but Flash is no longer supported on web browsers, so it's dead and outdated. Honestly have no clue if that's the issue or not, as I don't know how Doll runs her site.
The only solution I can offer is in the journal below, either that download I mention or look into the comment that I featured of someone else's suggestion. I don't even think it's possible to run flash on browsers anymore without downloading converters or extensions.
