Message box game crash

[someperson]

Ok in 1 of my games now, certain message boxes in the game will cause it to crash. I get error messages like it had to end, were sorry for your inconvience, etc. I checked the few I discovered so far and they seem to only crash when they say certain things. If I change the text or clear it, it will work fine. Example is if a message said dog, it will crash, but if I clear it to an empty one or change it to cat, then it will work fine. If I change it back to dog, it will crash again. *Note: Dog is just an example. I did not test if it actually crashes on that. It's to help you understand the problem.* I figured out I can test to see if message boxes will work by pressing F2 to preview it in XP(Ya, I'm useing XP btw). If it's one to crash in game I'll get a message saying "Critical Error C0000005 at address 0049783C" and then XP will close. I even tried the backup file of my project on an external hard drive from a few days ago. Same thing. I tried it in a different project, works but all that says is there is a problem in the current project. It was working earlier today, no idea why it is happening now. Any ideas on what exactly is going on and how to fix it? Help is greatly apreciated.

Edit: Ignore what I said how it works fine in other projects. That's only with previewing messages. It'll still crash in game.

Are you using the legal edition of RMXP? Sorry if that sounded harsh, but it was a common error in the old PK edition.

I was using PK, I transfered the project over to the legal version temporaly to see if it works. The preview thing still crashes though but I think if you export it as a game, then it will work fine. Need to test that.
