Digimon Rumble Arena 2 error

[x6tence]

Hello guys, sorry this is my first post. I was playing Digimon Rumble Arena 2 a couple of days ago like normal, it has always worked. I'm not really sure what happened but as of yesterday now I cannot play it. On start-up, it loads the file and then stays at a black screen with a window that says it is invalid to write to a location. If you close the window, it opens another one with a different location and does this in an infinite loop. Any help on this? Thanks for the help in advance.
