Here is the error message. At first, the report refreshed fine. Then it began to not refresh then gave the error Not a legal OleDate. So I decided to delete the report and republish. I also tried to delete the dataset but it would not let me. Now it is giving this error whenever I try to refresh the dataset. I have absolutely no clue what's going on. The report itself refreshes fine without any error.
Error:
