error message!!!!! OMG

Having trouble with LMMS? Ask about it here.
When I open the saved program
THIS message opens

Could not open file C:\Users\wldud\Desktop\±×Àú±×·¨¾î.mmpz. You probably have no permissions to read this file.
Please make sure to have at least read permissions to the file and try again.

How do I fix it???!!
Maybe by changing the name of the file.
Maybe the problem comes from the use of "special characters" ?
