Oh that? If you are talking about the "Profile Error Occured" error, that is normal. That's common in all RPGM games that are simply older than a prior RPGM game version you have. Here is how to solve that:
1) Go to C:\Users\<Your username>\Appdata\Local
2) Find a folder named nwjs and delete it
3)Go to C:\Users\<Your username>\Appdata\Local\User Data\Default
4) Delete two files named "Web Data" and "Web Data.journal".
After doing all that, relaunch the game and that pop up should disappear. It has a chance to reappear if you play a game that has uses a newer RPGM version so yeah... I've had that problem so many times before.
(If you ask me does that pop up appear when I launch this game, then the answer is no).
