Opening a Maya 8.5 model in 7.0
 

I just downloaded a model of a computer keyboard from Turbosquid, opened it in WordPad, and changed the "8.5" to "7.0"

The model opened fine, but I get this error message:
"Error: Cannot find procedure "localizedPanelLabel" - this is the decals for all the keys.

Is there anything I can do?

I don't know for sure, but it sounds like he might have done something 8.5 specific for the decals and 7.0 just doesn't support it. I'd say it'd be a fairly easy matter of just remaking the decals yourself.
