QuantLibXL error message when loading framework in Excel 2010

[Gavin08]

Hi,
the quantlibxl XLL works well on my machine (Windows 7 64-bit, Excel 2010 32-bit, both German editions). However, when I install the framework (no. 1) by adding the XLA as an add-in, the next time I start Excel I receive an error message:

"Error initializing the QuantLibXL framework:
createCellMenu:
getPasteSpecialIndex: Unable to access right click menu item 'Paste Special': Objektvariable oder With-Blockvariable nicht festgelegt."

Or see the screenshot below:


Does that have to do with Excel 2010 being incompatible with the framework? Or with my OS or Excel being German? Can you point me to a solution or a work-around?
Thanks,
Gavin
