Hey Boosted, no one's trying to make you look noobish. I know how frustrating it can be to have a problem and everyone keeps telling you that they don't see it. I've been there many times!
I only get the "cheats not allowed" message when I start a map normally -- that is, open up ET/fritzbot, select START, highlight a map, then select START SERVER, wait for the map to load, then type /god at the console.
If I then go into the console, type /devmap <mapname>, let the map load, then /god works for me. Or I can use the /devmap command from the console while in the ET menu system without going through the START SERVER procedure.
This is step-by-step what I do:
1. Start ET
2. Selecte MODs, and choose Fritzbot
3. When the map selection menu comes up, go into the console and type /devmap <your map name>
4. When the map loads, select your class
5. When you get out of limbo, go into the console and type /god.
6. Tell us if that works, or what messages you get.
BTW, you have to go into god mode every time you spawn -- it won't stay on thoughout a campaign. You'd have to do a /devmap for every map in the campaign as well.
Hope this helps!
