Hi folks,
I have a strange error with my MP 1.5 installation. Yesterday I tried for the first time to set up movie info grabber in the configuration and the list of grabbers is always empty.

I updated grabber scripts and internal grabbers and the list is still empty. In Configuration-Error.log I have errors that dlls are not found.

[2013-12-30 19:14:53,701] [Config ] [3 ] [ERROR] - Script grabber error file: C:\ProgramData\Team MediaPortal\MediaPortal\scripts\MovieInfo\Allocine_fr.csscript, message : error CS0006: Die Metadatendatei core.dll konnte nicht gefunden werden.

error CS0006: Die Metadatendatei databases.dll konnte nicht gefunden werden.

error CS0006: Die Metadatendatei utils.dll konnte nicht gefunden werden.

I have two machines, one with MP server and MP client in the living room and a desktop PC with MP client. After it didn't work in the living room I tried the desktop PC with same result. I reinstalled 1.5 and nothing changed. All three DLLs exist with date 2013-09-27 13:13

I upgraded to 1.6 and the problem persisted. Because I wanted to upgrade to MySQL 5.6 I did a complete clean installation and the problem is gone. Seems to be causes by some old stuff during upgrades. I started with 1.3 years before and upgraded to 1.4 and 1.5.

--- Edit ---
Yesterday I recognized a lot of 'access denied' in MP log concerning the scripts. It turned out that the scripts have no right set for the local non admin user I'm running Windows with. I changed permissions and the errors disappeared but in the configuration I had only one script without these access errors and that was the one I wanted to use. After playing with access control and editing the script to find out what's going on even this one causes the meta data library not found exceptions. I trying to set up a dev environment on my desktop where the same problem occurs. I keep you informed.

    Same here, the problem persists.

    After the update to 1.8 i had the great idea to renew the video database after a long time.

    unfortunately without success, similar old updated installation like uxDesign
    same blank menu and error message:
    error CS0006: Metadata file 'core.dll' could not be found
    error CS0006: Metadata file 'databases.dll' could not be found
    error CS0006: Metadata file 'utils.dll' could not be found

    I use it not really but it's nice to have it if it works.

    Hi, check for this lines at start of script
    //css_reference "core.dll";
    //css_reference "Databases.dll";
    //css_reference "utils.dll";
    The references are necessary before using it.
