Opening game file help

Well, I tried to open the games Project file but when I click it, it says this



What to do?

I've never seen this error.

I have no clue whatsoever.
Maybe the project data and your RMXP has different versions ?
It does that in different version.

But I think the words are different.

Well, I think I have an idea what happened, turns out I opened the 'Items' file in the Data folder in notepad, its blank, but the others are full of symbols and letters. So that MIGHT be a problem.

If you didn't really add much item stuff at all, just copy and paste from a new project, maybe.

I'll try it right now.

EDIT: Now it says WEAPON data is messed up...I guess I just keep going until its fixed

Keep Going.
