Try the Harmony client. It may be able to offload the Actions file. Also try doing a Restart (NOT RESET), then try offloading the Actions file. If none of that is successful, you can try deleting all the Actions and see if that will get you to an Actions file you can offload. The final solution is to do a RESET but that is drastic, clearing all the xml files. Before doing a RESET through the Server Configuration function, try offloading all the other xml files so they can be reloaded after the RESET.
