i tryed uploading my own back groud but all it says is Your file does not seem to be of the PNG MIME type, so you cannot proceed with this upload.

 

 

 

Your file does not seem to have the PNG extension, so you cannot proceed with this upload.

 

 

im not a good computer person, so help plox!!!!! :pray:

Your background isn't the right file type.

 

 

 

Open it up in Microsoft Paint (I assume you have Windows) and save it, then when a little window pops up, choose where you want to save it, and select '.png' under the drop down menu of file types.

 

Then try it again and it should work.
