I receive the following error when opening a Web Intelligence Document, no matter the user.

C​a​n​n​o​t​ ​i​n​i​t​i​a​l​i​z​e​ ​R​e​p​o​r​t​ ​E​n​g​i​n​e​ ​s​e​r​v​e​r​.​ ​(​E​r​r​o​r​:​ ​R​W​I​ ​0​0​2​2​6​)​ ​(​E​r​r​o​r​:​ ​I​N​F​ ​)

I also cannot run any reports. Anyone have an idea? I cannot seem to find any information in the knowledgebase on that error.
