Back download doesn't work with Google Spreadsheets

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Upload a database to Google spreadsheets
2. Try to download it back to Anymemo
3. Get an error message

The way to download database back is to remove sheet named learning_data from 
the spreadsheet. But we lost all learning progress then.

What is the AnyMemo version (E.g 8.999.1, 9.0, 9.1.1)?
10.7, 10.6 and previous

I attached the error message pop-up
