View source for Keystone: not Opening ./skin/keystone/Video.png: file does not exist

MXWendler version lower than 5.2

'''Problem'''

You open a keystone file or project with MXWendler and an error message appears that says ''not opening ./skin/keystone/Video.png: file does not exist''

'''Solution'''

Ignore this message. This is not a technical problem. All keystone and other functionality is still available.

'''Background'''

You saved an .mxw file with Version 5.2 and higher and opened it with a previous version. Version 5.2 and higher changes the internal storage format for keystone files. Versions 5.0 and lower are looking for helper textures, in this case 'Video'. The 'Video' helper texture does not exist in these versions.

Among different versions, forward compatibility is guaranteed, backward compatibility is not. Keep this in mind when programming systems.
