Hi mendesjpcrs
As others have said - MMM is not supported anymore.
There was many problems with ctds during the making of it.
I do think that for many it worked well - but for others ...no
Not sure if you have added any more mods to it, but you should post your mod list.
Your specs are ok to run OHII full

You should try it on its owns and see if you get the same issues.
If not build you mod list from that.
See my balanced mod list (sticky) or try Sobers - he has spent many hours getting the correct mods in the correct order
