Atari2600/7800 not working? Need help fixing blank screen

So I've downloaded and installed the 8TB. Install was pretty straight forward. Anyway...I thought I'd test out one of my favorite game Centipede. Launched fine but all I get is a "blank white" screen. Don't know about sound as I haven't attached any speakers to the computer yet.

Some of the things I've tried so far are:

Run the Syncovery Update - can't update as it keeps telling me the "Server is unavailable".
Did the file comparison. Looks good.

Any ideas?

Thanks,

Matt

Oh...one more thing that I tried is launching the game through the RocketlaucherUI. Still getting a blank white screen.

Issue has been resolved by running the Sync Update.

Admins, you can close this as solved.
