Ok guys, I have checked the file available in the downloads area of the Toontrack site and started the installer. It immediately told me that there was a more current version on my computer. This more or less confirms to me that the file on the TT site that is available is an earlier beta and not a finished version. That doesn't mean it's going to blow up your system if you already installed it. I would hold off until a bit and see if there is any sort of public announcement about it. The TT forum is all but hosed and I have made contact through the betatest team access to see what is going on. Unfortunately, I suspect most of them are asleep at the present.
If you installed this version of EZD2 then EZD1 is overwritten. IIRC, all of my EZX kits were still functional but not updated to where the cool new presets and graphics came into play. You still should be able to work on projects.
If you have downloaded the EZD2 files, I'd advise you to hold off till the real release is ready to go.
