I can confirm that this is the behaviour. I am using the latest version 
(0.7.6.187). I suppose it is because Google dropped support for .doc and .xls 
and uses .docx and .xlsx for exported files. The problem is that I cannot open 
docx files with MS Office. When I double click on the downloaded file, MS Word 
says it is corrupted. I have also verified that downloading the file in .docx 
directly from the browser works fine.

We have the same problem (GDocBackup 0.7.6.187, Windows Server 2008 R2 64Bit). 
I've created a second task to rename all xlsx to xls. 
Do you still need more details?
