Bundles that I create with ZPM have not been working for us for awhile.

The vast majority of bundles fail and log the following "ActionMan.CachedItemError" message in ZPM:

There is an error in cached information for id <<Bundle Name>> The content is not yet available to download.
Additionally, users have been getting a long narrow popup error from Zenworks saying:

Failed to launch: Could not find the file "C:\Program Files (x86)\Novell\ZENworks\work/content-repo/tmp/zpm/plp//windows/C513513D-0069-48C3-A8FD-4B01B687BD63.plp" to install.
After clicking "OK", the error continues to pop up about a dozen times, with just the PLP filename in the error changing each time, before finally no longer popping up. Not only is this quite annoying for the user, but more importantly we're behind on our patches. I've searched around but I can't seem to find anything they changes this.

Any direction would be much appreciated. Thanks for your time and help.
