Export Finished Design

[avalier]

I have a finished design and want to export. However, I get a notification box that states;

[The given filename does not have any known file extension. 
Please enter a known file extension or select a file format from the file format list.]

That was it, thanks.

Can you tell me, When I export this image it is on a transparent background and the PNG has a black background? If I use Black Text, it cannot be seen on the PNG. So if I  send this off to a printer, there is no text, and will the black background be present which will mess up the printing because I need it to be Transparent.

If it has a transparent background in Gimp and you export as a png the background will still be transparent. If you send it to the printer it should (hopefully) be correct.

However, different programs display transparency differently. Gimp displays a check pattern, some display it black and some display it white. Even worse, some remove the transparent background and replace it with white (eg facebook).
