Other than what Lutz said about a timer, I think your code should run just fine, you could simplify it thou, and because you would be closing it (if necessary) and opening it in the same sentence this might help, as it will not be interrupted by a timer, AFAIK

If !File(xlngfile)
	Return nesne
Endif

Use (xlngfile) Alias Language Again Shared in Select('Language')
select Language && if you need Language to be the current selected table
