OK, now, let us excercise this through using a savegame of one of your games:
Please do everything exactly as posted here. Don’t do anything else or different.

Right-klick on “Savegame” and choose something like "Save link to… " (Sorry my system is German)

Now, in the follow-up screen choose a place on your drive you will easily find and hit “Save”.
I place it in D:\download

Now you can close your browser.
Now start TripleA by doublecklicking the TripleA icon (NOT the savegame).
You are here, now:

Click “Open Saved Game” on the left side and choose your savegame that you saved before. Click “Open”.

This is how the TripleA screen looks now: Note the savegame appears on the left side, marked yellow, here.

Now hit “Play By Forum” on the right side. This is how the TripleA screen looks like now:

Be sure that the credentials are filled in - but apart from this don’t do anything else on this screen than hit “Play”. Especially don’t hit “Test Post”.
The game opens (or should open) fine now. At least it does here.
Good luck!
