So yesterday, I stumbled upon the license for this device with 10 Mbps throughput, for $96 on CDW's website:

I was going to buy the license previously which was for version 11.3, which they discontinued a couple of months ago. The thing is though, the VE trial they have is still on 11.3. Anyone know where I'd get the current image from? I bought a license, so I'd assume they'd provide that somewhere.
