Now That’s a Fine Mess You’ve Gotten Me Into

I asked him when he handed me the disc… is this legit? I was assured that it was.
More Fool Me.
Here I am 2 and a half years later having purchased the upgrade software gone to install it and found that it isn’t going to be so easy as I don’t have the one serial number I need. The reason I don’t have it is because the person who gave it to me neglected to mention that while it was a legit copy of the software it was actually registered to him.
That being the case were I to be using it legitimately I should in fact be using it on a computer he owns in his employ.
So I contacted the vendor who sold me my upgrade and asked if there was any way it could be returned for the full version.
Apparently not.
Now, if this was a simple case of a $40 or $50 unit I’d be ok with that… but this is MYOB Accounting, the upgrade was $225… The full version is $285. So now I’m stuck with both. And I’m really unhappy about it.
Can Anyone Say Ebay?
