That did it! Thanks for staying with this C-Beats, Steam games are now loading up fine. I must say that I really like this front end, it's miles better than Gog Galaxy! Thanks again for your help!
PS: I noticed that quite a few people are having this or a similar problem? Maybe a simple explanation of what should be entered into the Custom URL field, instead of enter a value, something like enter any user name you want in the box! Just a thought?
