Hi, In order to be able to assist you'll need to let us know which version of the Dark Heresy character sheet you are using. A screenshot or two of the problem is aslo usually very helpful. I've had a quick look and noticed three versions: I notice the last character sheet explicity mentions requiring APIs to use, so if you're trying to use that one and you cannot use API scripts, that would be the issue: If this is the sheet you're using, you have two options: 1. Update your account to a Roll20 subscription that allows the use of APIs, and install the APIs required. 2. Switch to a different character sheet that does not require APIs.
