for the menus, be sure to delete the .mnr files before starting acad, they are right next to the .cuix.
Do you see the toolbars in the CUI tree though? If you can load the menu but not see them, you have an interesting problem. In general though, cui's from previous releases load into new ones.
Be sure if you have images or a .dll for them its present in support paths.
BTW, why anyone would store custom menus in cui or cuix files is beyond me.
THe original .mnu format is so much better as its text file based, not CUI, and just always works.
Once you go cui, you are stuck with any mistakes adesk makes in reading or using them, like you might be right now.
