I used live update to go from build 199 to 200. After the update when a subscription runs an error with no details is logged in the Subscriptions History tab. Nothing is logged in the windows event viewer.
I ran UpdateDb.vbs and verified that the DelivFilePattern column is present in the job table. However there is no change, subscriptions are still posting a blank error message.
The issue seems to be isolated to subscriptions that with a content type of PDF. When running OLAP reports with a PDF content type I get the following error:
Could not load file or assembly 'itextsharp, Version=4.1.6.0, Culture=neutral, PublicKeyToken=8354ae6d2174ddca' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
