language file not valid

The language file 'x.spr' is not valid for version 'x'!

This message appears if the software locates a language file (*.spr) in the SPR directory which is not valid for the current version of the SAMSON Valve Sizing Program. This could be the case after an update to a new version of SAMSON Valve Sizing, and the SPR directory retains old SPR files which are not included in the new version. The SPR directory can be modified under the Direct. and aliases menu item of the Preferences menu.
