Some users reported this... for some not_yet_discovered reason and under unknown_for_me circumstances, when you add stuff to your collection and then open the content manager or some collection browser, it throws up this exception.

In one particular case, the problem was with the antivirus (NOD32). In another, by closing icomancer and reopening it again before accessing the content prevented the exception. In yet another case, by simply running icomancer as administrator (even with a UAC-disabled admin-privileged user logged in) stopped showing up the exception.

Please check your security levels/try to run icomancer as admin and reply if you still get the problem or let me know if that fixed you up.
