...it says its been installing for over 30 minutes. No luck. Panini DBZ on a Windows 8 machine.
Installing images can take a very long time depending on the size of the pack(s). You can use all other features during this process however, as the built in card proxies can be used for play/deck editing, and will be replaced with images as they are loaded.
If it fails, or does not finish installing the images, trying again after restarting may help. If that also fails, there may be a problem with the formatting of the pack or it may be corrupted somehow. in this case, check for any corrupted data and re-obtain it(or start from scratch if that's easier) and also ensure the pack matches the formatting outlined here: https://github.com/octgn/OCTGN/wiki/Card-package
Hope that helps!
