An image format is illegal

[WisK]

Every time I try to test my game it tells me "An image format is illegal" Im sure what that means or what to do because Ive cheacked every image file in my RPG2000 folder and their all .png fomat. So what do I do here?

Did you import all the files throught the file importer? Usually that would filter out what's wrong with it.

File importer? Whats that?

Lol, see, there is your problem already.
On your toolbar their should be something called a "Resource Manager"
click that and select the folder that matchs the file that you want to import.
Them click "Import". If it can't use the file, it'll tell you what's wrong with it.
