BPC DeleteOlapDimFromCube error and Analysis Sevices error (-2147221421)

Attempted to process a dimension in BPC and encountered the following error message:

-DeleteOlapDimFromCube : Item not found in collection

-Dimension is locked because it is currently being used in a cube. Remove the dimension from the cube

Went to Analysis Services and successfully procesed the dimension and all but one of the applications.

Error message recieved was:

Error(-2147221421) Internal error could not update the query log.

Any ides?
