I had created a test Metric under Weekly Metrics. I deleted it and now I can no longer see any Metric. When I try to drop down the Weekly category I get the object reference error. I know the metrics still exist because I can see them in SQL. Even if I create a new metric I do not see it in the metrics tree. I tested the block settings against the Demo and tried recreating the block but got the same results. Any ideas would be appreciated.
