Hi All ... I see that a lot of people are having these type of problem.. Here is a solution that i found ... Do not disable any thing in MCM menu .... it only stops the error message. If u get and incompatible menu file error just go in you skyrim directory -> Data Folder -> Interface. Find the file name that was in the error message like for example favoritemenu.swf . You just need to cut this file from skyrim interface folder and make a 'interface backup' folder anywhere and paste it in that or if you want to delete it , your choice but i highly recommend to make a backup instead of deleting it ... Same applies for any ERROR CODE 5 in SkyUI .... This word 100% and you will see the SkyUI menu the next time you start the game. I hope this will help you guys ..
