Yep, had the same problem - but rather than opening it, I saved it to my hard drive. Then I was able to extract it and open the .nfo file.
These problematic devices could be the source of your problems:
Realtek RTL8168/8111 Family PCI-E Gigabit Ethernet NIC (NDIS 6.0) PCI\VEN_10EC&DEV_8168&SUBSYS_E0001458&REV_02\4&2EA914C&0&00E4 This device cannot start.
Realtek RTL8168/8111 Family PCI-E Gigabit Ethernet NIC (NDIS 6.0) #2 PCI\VEN_10EC&DEV_8168&SUBSYS_E0001458&REV_02\4&30A2D01F&0&00E5 This device cannot start.
-Download fresh drivers from the Realtek website here: Realtek
-Uninstall the current Realtek software/drivers using Control Panel...Programs...Uninstall a program
-Go to Device Manager and right click on the problem devices to Uninstall them.
-Install the freshly downloaded drivers.
This unknown app may also be causing problems: CSL_PCAPP_LB_2_61_09.exe
Do you know what it is? If not, could you search your system for it to see if there's any clues?
I suspect that it's a Creative Console Launcher Web Update - but am unsure
