Can not save network profiles

[mross]

I have just updated to 2.5 (eventually). In the process I deleted the 2 network profiles. Now I can not save any new profiles and so can't connect to IDS. Test connection works fine for wired and wireless connections and DHCP table on my router shows 'ereader' has been allocated an IP. I think 'test' connects to the IDS server but when I press the 'connect' button for 2 seconds it is always 'unsuccessful' - I think because it can't find a network profile to use.

I phoned support and they said to save the profile name with CTRL + s but that does not work.

Anyone know if there should be a filename extension like .cfg that I should try?
