If you have problems with Adobe DPS local folio cache, here is a script which deletes the local caches:
This script deletes temporary Adobe Digital Publishing Suite Caches on your local user disk.
If you are experiencing problems with sign-in or corrupt folios, the cache might be corrupt. Please read this topic: http://forums.adobe.com/message/4272296
I do not give warranty on any script or am reliable to failures due to the script. Please be aware that the path of Adobe DPS' cache might change and script won't run in future after such a change or might affect other applications that might use the same folder (which is very unlikely because it would cause a conflict).

Feel free to use. Of course I appreciate mentioning my name :-)
Now, check it out. Download the script and App here: Download
