Converting back to old KMA files

[kjunkies]

I have an issue which is probably a little different. I upgraded to 4.11 when it 1st came out and love it. I keep all of my songs on the C drive of my laptop. Because my backup home computers are extremely old I have left it with the 3.32 version which I use purely as a backup and to try songs out. I have two hard drives which I use on the backup home computer and I lost both drives within a few weeks. I bought another hard drive and thought I would just copy the KMA files from the laptop over to the new hard drive but when I tried to rebuild the database it became clear that 4.11 had converted the KMA's to something a little different which could not be used on the 3.32 version.

My question is... is it possible to convert the KMA's back to the version that will work on 3.32? The only other option is to upgrade the backup to 4.11 as well but my backup computer has no where the min requirements that you suggest you need to run it - will the newer version just be a lot slower on an old computer or will it not work at all. It is all good if it is just slower (it is only for practise).
