cam2pc 4.0.1 Image Browser - Anyone seen this problem?

When using the image browser, the program works great when browsing
directories on the hard drive. However, when I inserted a CD that
contained directories (directories created by a previous
version of cam2pc) of photos the left hand pane showed the
individual directories of the CD but the right hand side was
empty. When I clicked on one of the directories, a message
box popped up saying "The parameter is incorrect". It
is not possible to view thumbnails of ANY CD and the only way to
view the pictures on the CD is to select "slideshow"
or "fullscreen". I then opened cam2pc 3.0 on the same computer
and was able to view the pictures just fine.
If anyone is having problems like this please let me know, perhaps we can isolate common denominators and figure out what causes it.
