Lightroom 3 does not export images to Photoshop CS5

Question

After updating to Lightroom 3 and CS5 I can no longer send nef or dng-files to Photoshop from Lightroom (Photoshop works perfectly if I load files from Bridge). When I select an image in Lightroom and try to edit it in CS5, Photoshop starts but does not show any image on the screen. Calling Photoshop from Lightroom seems to work, however the file export is missing. This happens both with the "edit in Photoshop CS5 and "edit in Photoshop" option. I have checked the registry entries for photoshop.exe in the registry - they are correct. I use both programs on Windows 7, 64 bit.
I am almost desperate as I have searched the internet and tried out many things without success.
Grateful for any helpful response,

I had this problem with some images, and after much playing about, I found it was because I had an '&' in either the filename or the folder name. If I deleted the '&' from the filename or foldername the files opened in CS5.
