I downloaded Beta 3 and 4, tried to open it on a Vista Notebook, but it never starts, always says there is a problem but doesn't say which one and just doesn't open. So I can't even try to put ATV on there... is there a nother option to get it going? Could you include it like Cydia or something when you jailbreak it and activate with the acc info?! That would be nice...
It sounsd very much as if you have a corrupt download.
I would suggest that you first clear the browser cache, and then retry the download. Alternatively you could try downloading on a different PC if you have access to one.
I don't know what the problem is... i tried it on a different computer though and it at least started... so i will use that computer now... thx for the input...
