VDJ PRO FULL works really well with the Ergo, where is a little bit of set up to do to get it how you want but for most users all you have to do is uninstal the LE version and install Pro and it works spot on. I am using it with the CDJ850S and have got to say they work the best with VDJ PRO than when I have tried with the other DJ softwares out there.
If you have got any worries and thoughts though pop over to the VDJ website register your LE software and you will get all the help / advise and support you need. Not to mention a discount on VDJ PRO as you have an LE version already.
Hope this helps
