I use the demo. The only category you can run is No Added Rules Standard but if that's up your alley absolutely go nuts

You have to put containerridesave.sav into your SAVE folder (properties > browse local files > portal2 > SAVE > bunch of numbers unique to steam id > put the .sav file here.

After that, restart Portal 2, and type "load containerridesave" into the console once more.

Hope this helps.
