i downloaded ssjheero bruma MG restored, threw it in the obmm and the game wont start.

If the game won't start it's generally due to a missing master. Three main causes:

-You've enabled a file without checking to see if all it's masters are enabled
-Batched patch wasn't rebuilt
-Land magic wasn't run

If you have Wrye Bash you can quickly find the offender by loading it and finding a mod with a red box by it. Click on it to see which master is missing.

looks like a hassle, even choosing a wrye brush file looks in itself to be a directory of choices, the read me says * off. I'll just let bruma mages guild stay in eternal fires.
maybe someone made a seperate building for mages that anyone can add.

Looking at the mod, my guess is that you installed BrumaMGRestored-Frostcrag.esp w/o having DLCFrostcrag.esp. That will cause a crash on startup as you're missing a master.

idk guys, having the frostcrag.esp file seems more like a requirement. If that guy is handing out mods then he probably should dress up his download info a bit more on the install side. Under his history and known bug issues he gives reference to a frostcrag teleport file. Is that the file I need ? or did he borrow some or something from that mod to help his creation. Its not real clear language, more like "implied" installation instructions because he has bits and pieces of it what you need to install it are actually under the category of: Known Issues + Bugs & History. His intsructions arent all there.
Tes Nexus has more to offer than that so I'll move on. just making an observation.

If you do not have the Frostcrag DLC, you will crash on startup when running that ESP.

From the readme: "If you run Frostcrag Spire, also enable BrumaMGRestored-Frostcrag.esp." So a simple deduction would be to not enable it if not. :shrug:
