There's your problem right there, it's been flagged as pirated / stolen, you only have yourself to blame, read the EULA, one pc per copy of Windows.
You can not use it on multiple computers, you figured wrong.
Activations are unlimited if it is on one pc at a time, I'm still running my original copy (which was brought when XP first came out, it is SP1) and I've lost count of the number of times I've activated it.
The Acronis image would only work if the pc's have identical motherboards but that point is moot as you would still be breaching the EULA which is effectively BREAKING THE LAW.
