Login to Hamachi using IPv6 times out

Question

My cable modem uses IPv6 and so does my LAN. I want to connect my laptop to the hamachi service. However, the laptop tries to connect via IPv4 and this attempt fails.

The network configuration of my laptop looks like this

wlan0     Link encap:Ethernet  HWaddr 00:1e:64:47:00:cc  
          inet addr:192.168.0.13  Bcast:192.168.0.255  Mask:255.255.255.0

and according to the config file IPv6 is enabled

$ cat /var/lib/logmein-hamachi/h2-engine.ini

However, the service is resolved to a IPv4 address and connection to this address takes very long and then fails (probably because IPv4 is used):

01.11 12:23:47.193 ses: reconnect delay: 389 sec

I already tried sudo hamachi set-ip-mode ipv6 but this does not change the fact that IPv4 is used.

Is there any way to make Hamachi work over IPv6? Any help would be appreciated!

PS: I use the latest version of hamachi: 2.1.0.119
