nightmare scenario, I had the same problem, just what is
the story with this flaky Micro$oft software.
Anyway...the below fix should sort out any RRAS probs
where you get this message (Im guessing yours is same.)
"The port information cannot be saved.
Cannot complete this function.

1. Open the registry edit START > RUN > REGEDIT <ENTER>
2. Locate the key HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001
\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
3. Sub-branches (or folders, im not sure of the exact
term)under here will be shown as "0000" "0001" "0002" and
so on. if you select each of these in turn and look for
the "DriverDesc" key on the right hand pane until you
locate the one that matches the description of your
particular modem thats causing all the grief.
4. Once you've found it, again on the right hand side,
look for two keys. The first is "EnableForRas" the second
is "EnableForRouting".
5. For the sake of explaining, setting the value
of "EnableForRas" to 1 enables The device for remote
access, setting "EnableForRouting" to 1 enables the
device for routing (for dial-out). Setting either of
these to 0 disables the action. I have not tried and do
not recommend trying any other values other than 0 and 1.
If the EnableForRas or EnableForRouting keys arent there
then you will have to create them and give them a value
of 1, then reboot.
