ITunes Match won't recognize my MBA equipped with a new SSD

Question

Hi,
Here's the situation: I replaced the SSD in my late 2010 MBA to add storage space. Everything went perfectly well and I have been using it for weeks, no problem whatsoever with any of my iCould stuff - calednar entries, contacts etc. as everything was transferred over by making a back-up of the old SSD onto the new one and re-instlaling Mavericks to the new one.
I also have been using iTunes Match for years and love it: ATV, IOS devices are all connected and work perfectly. Until I tried using iTunes Match on the MBA equipped with the new SSD. Note that my iTunes music (not the library file) sits in an external drive connected to my Home network which I don't currentl have access to. That's also teh reason why I signed up for Match: once synced, I didn't have to connect to tht drive and could travel while still having access to all my music.
The library only sees two local songs that were downloaded recenrly after I purchased them on the iTunes Store. I'm still using the same Apple ID nothing changed, but iTunes isn't showing any of my iTunes Match songs in there. I checked Match had been turned on (it is), I checked that I didn't max out on the number of devices (I haven't) and even checked availability of iTunes Match in other countries (temporarily in France), but otherwise residing in the US.
So now, when I try to "add this computer" to iTunes Match, it gives me the following error:
Only one library can be matched at a time. If you continue, the other iTunes Match session will be stopped and this computer's library will be matched instead.
=> Seeing that the "old" library and the "new" one technically come from the same Mac (only now it has a new SSD drive), I'm at a loss and scared to have all of my previously synced/matched songs deleted from itunes Match if I only sync the two local files that were just downloaded/purchased.  <=
Would appreciate any help or suggestions please.
Thank you in advance!

Hi,
You often get this message when match thinks that you already have a match in progess on another computer.
If you are happy that all your music is on your new hard drive (or if it is only in the cloud), you should select "this computer".
