For Ad Hoc I always "hard code" my IP addresses - use static/assigned ones, not DHCP. I don't know that TVersity does DHCP within the software itself, but you should have no problems using static IPs for Ad Hoc. Just make sure both exist within the same subnet, as in:

TVersity assigned as: 192.168.1.30

Nokia assigned as: 192.168.1.31

with both using the same gateway (I tend to use the other device as my gateway but this is not likely the right thing to do) and mask (no need for anything beyond 255.255.255.0) so they more readily find one another.

If your TVersity box is already configured (it should not be using a 169.254.... address) you should configure your Nokia to similar details as stated above.

This isn't a how/why answer, for that you can find those answers anywhere on the web if needed.
