problem

Choosing detect language in InstantTranslate text translation tab, then changing to file translation shows an unnecessary and misleading error message.

1. in TRANSLATE TEXT choose detect language
2. click on TRANSLATE FILE
3. source language changes to a language
4. error message is shown even the language combo is valid

solution

A valid language combination must be chosen, no or a proper message must be shown.

Proper message would be: For file translation a source language must be chosen.

It should be investigated (and fixed) why this error message is shown after the above described sequence of steps but is not shown if no 'Detect language' is selected before switching from text translation to file translation
