baldure on "[Plugin: Visual Form Builder] VFB Pro XML error when exporting entries"

I also have problem with 2.2, but a different error message:

XML PARSE ERROR:  Malformed or illegal attribute name
  Error occurs at or below this element stack:
    <ss:Workbook>
     <ss:Worksheet>
      <ss:Table>
       <ss:Row>

I can get the data out with CSV allright, but that's not the same is it?
And in excel I can't seem to get the encoding right for the CSV file, all my special icelandic letters get messed up even if I try to open it as UTF8.

I can however open the CVS file in Libre Office with the right encoding!

I see the excel problem both on my Mac and on a Win7 box.
