Yes ... download Digital Rebellion's FCS Maintenance Pack (15 day free demo) and open the project XML with the "XML Repair" tool, then from the menubar choose Tools menu > Convert XML Interchange Version ...

Then whoop for joy, consider how useful it would be to have such a toolset available to you for longer than the 15 day demo period, and buy a license ... awesome tools by awesome developers need to be encouraged and supported.
Btw, the chap behind Digital Rebellion is Jon Chappell, a regular and valued contributor to these forum ... so if you see him be sure to say "Thank you".
Cheers
