This error has been appearing a lot. Does anyone have a solution?

Which game? I don't intend attempting to download every game on the server in the hope I may find the one to which you are referring.
Are you using the online player or downloading and running it locally?
If it won't work online, are you able to download it and play it on your desktop?
Are other games loading Ok?
Any other relevant info that might help someone to help you would also be an advantage.
