Just a FYI, some have been able to downgrade and it work. However, you have to be prepared for that beforehand I think. I've seen it posted before but can't recall WHO it was. I was hoping they would reply but either they didn't see your post or they are no longer subscribed. While it may be possible, it is risky and not recommended. It's one thing that I wish they had a known path to downgrade for. It's one of those, you don't know it's going to break something until it does and you have little or no options. Glad you got a workaround tho. Maybe some more info will pop up later. Dale :-) :-)
