Reactor Room troubles

[G0DF47H3R]

I backed up my original carousel map and copied the RR file and pasted it in the maps folder. I then opened ppf-o-matic3 and applied the ui.ppf patch to the ui.map file. I am able to play it online as long as I host but when I go to join another server it gives me the exception notice we all love so much. I have been able to do just fine with all other maps so I'm not new to this. Anyone get the same issue? Or can anyone help? Thanks
