Dear T.T.S.

I have downloaded this platform via Steam and started playing online with friends. The first 2 scenarios of Gloomhaven - Jaws of the Lion downloaded fine, I was the invitee, they played smoothly, and were fab. Thereafter every scenario downloads to about 90% before an error message pops up stating 'WWW Image error: unknown error'. The player board area remains blank, although various icons appear on it, and the game is unplayable.

Since then I have tried hosting this game, and have also tried logging in as a guest on several other games (Welcome All Heroes, Frosthaven etc.) but the result is the same. I'm now also getting another message 'WWW PDF error: unknown error'.

I've tried lowering various graphics and other settings to reduce the demand on my laptop, but to no avail. All my other games on Steam work fine.

Any ideas to help please?
