Thats not a script failure. If you can see the values in the CUSTOM fields the script correctly downloads the informations (this is my "backdoor" ). I think this is the same "bug" as with the IMDB Details 2 which are not visible (I think this is a database issue).
For clarification: The (API3) scripts are for XMM7. The (API3)_for_Rel_8 scripts are for XMM8!
The current versions are: Movie - XMM7 -> v1.6.4 (on XMM-server v1.5.1!) Movie - XMM8 -> v1.9.3 (on XMM-server v1.8.1!) Actors - XMM7 -> v1.2.4 (on XMM-server v1.2.1!) Actors - XMM8 -> v1.2.4 (on XMM-server v1.2.3!)
