[Error had occurred and could not activate the selected cartridges.]

LOL! Sorry about that! :-)
Your best option is opening a case with support. You can take a look at the mgmt logs located in the vFoglight\logs folder to see what error might have been thrown.
You can try copying out the .car file (eg...Chargeback-5_5_4.car) from the vFoglight\cartridges folder.
First try pointing to the copied car file and installing.
If that does not work, then try uninstalling the cartridge from the cartridge inventory view. Next, point to the cartridge file you saved out and install it.
