What is the file-name of your primary script file? Main.C or Main.wdl ?
If it is main.C, then make sure main.wdl doesnt exist.

WDL files can be used for "starter window" definitions,
eg "WINDOW WINSTART { ... }", which I think are a PRO-only function...
So if you are using lite-c, beware of any 'unplanned' WDL's floating around
as they can cause havok at publish time.
