??? signs mean either a plugin that is not available for your license (though I think that's only for PDF tools in version 7) or for custom plugins that were used in your process. In order to resolve this issue, you would need to go in the old machine where you had Watch, in the following folder:

C:\Program Files\Common Files\Objectif Lune\PlanetPress Suite 6\Plugins

Generally "custom" plugins are the ones that do not have any extra files with them (.en, .fr, etc - the language files), but if you're unsure you can simply copy all DLL files here into the same path in your new server. When asked to overwrite the DLLs, choose "no" for each - so you will only copy the new DLLs over.

You'll need to close and reopen Watch to see the plugins again.

Hope this helps,
