I can't sync my iPod Touch because of "Unknown error (13019)".

Question

I can't fix the problem without losing my music because I manually manage my music. I looked online how to fix it, and even called Apple, and no-one seems to know what to do because if I use the ways that I was told, I will be losing all the music on my iPod that isn't stored on my current Computer.

Hello to both.  Very good question, hence the 24 hours spent finding it.
I noticed that the total number of songs in itunes, (laptop), differed to the number trying to be synched to the ipod.  After trying just 1 album, which synched perfectly, I tried 2 - ok.  So then 5, then 10 and at 25 albums, error 13019 appeared again.  Then just working back, 1 at a time, there was an album containing a 1 song download, later upgraded to itunes plus, which was in the windows music folder twice - once the original m4p version and also the new m4a version.
I highlighted the "m4p" version, right-clicked and selected "delete".  The subsequent synch worked perfectly and I've had no troubles since.
Reading the on-line pages, it seems there are probably multiple causes of this error.  This was the cause in my case.  Whatever, don't give up - it's probably as simple as this.
Cheers!
