Rpg Maker Developers Group

Hey guys. I am just new to rpg making, and so am new to this forum/group also. 


I was just starting to create my game, and just like that, as soon as I hit Playtest, it gives me this error.


'TypeError undefined is not a function.


I have just updated my mv from 1.3 to 1.3.1, and of course I did the precautionary measures of backing up and copying the newdata files and everything else to be done before updating.


I think the update went just fine. 


Then I opened my game and as I've said, the error keeps showing up. 


Note: I didn't had this error before I updated MV. The only plugin I have installed in my game is the MadewithMv splash screen plugin that came from updating to 1.3.1


My game is just starting to be built, I mean, I am just starting to create the game then this error appeared after I updated. But I don't necessarily think that the update has something to do with the error.


Please Help.
