DVS Ultimate with umix-44 installation

I have had issues with the installation of DVS Ultimate.
Firstly, i attempted to install it on my laptop, to which it worked the first time through, then turned off my laptop, the next time i turned it on it was only working though input/output 2. I wired up my turntables reversed and it remained channel 2 that didn't work. I un-installed and reinstalled and it wouldnt work. eventually after repeated uninstall/reinstall it worked, then again, once i restarted my laptop i had the same issue. So I uninstalled once more and now it fails to install at all!
I've realised that my external disc drive has broken since i first used it too install. Is there a way of downloading the software?
Even if thats possible, how would i solve the initial issue?
Thanks
