Just a FYI, some have been able to downgrade and it work. However, you |
| 33 |
have to be prepared for that beforehand I think. I've seen it posted |
| 34 |
before but can't recall WHO it was. I was hoping they would reply but |
| 35 |
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 |
| 38 |
thing that I wish they had a known path to downgrade for. It's one of |
| 39 |
those, you don't know it's going to break something until it does and |
| 40 |
you have little or no options. |

Glad you got a workaround tho. Maybe some more info will pop up later. |
