Sweep - the problem is that 2.5 is very different than 2.0.2. Downgrading without removing the AME tags will result in the problem you are experiencing. Im not sure why your test post isnt converting correctly other than remember that the conversion tool is just a 'tool' for helping you to remove previous media systems. The problem you are having (if I understand correctly) is in converting a post that has an old media tag and an ame tag in it. My guess is that either AME isnt recognising the previous tag or it is skipping the post because there is an ame tag already in it. Regardless, all other areas should be functioning as intended considering its a pre release
