File pre-scanning error when creating project

Hi all

The following warning messages were generated when trying to import files into a new project:

"PreScanning failed to identify file type, the following messages were generated:

PreScanning Error The document is not bilingual since 'tw4winMark' style is not defined."

I am perplexed, since the file is  a normal .doc file, and it should not be bilingual as I have not yeat started translating.

I would appreciate any help.

Regards,

Suvi
