Did you ever get an answer to this?
I'm working with FMA 10.0v3 and I can't find my Import.log either. I'm working on a local machine with Windows XP/SP3. I searched all the associated drives and didn't find anything.
I'm importing from one FM file to another. Both were created in FMA 10. The dialogue box says it imported 169 records with 1record skipped due to errors. However, I only get 147 records imported, some with incomplete data or empty fields. This data does exist in the file I'm importing from.
Where is my Import.log or how can I generate one? This is also happening to a friend using FM 10.0v3 (not advanced) on his FM server.
