7.5.1 can not find RR

[mr.prick]

i installed 7.5.1 and updated the firmware,and the RR could not be found so,
i uninstalled the drivers with the FTClean and reinstalled them.
after doing this 3 times

i found that version 7.4 (A.K.A 7.5) would connect.
i have added 7.5.1 to my firewall and i still can`t
figure out why it won`t see the RR.
also the RR filters have not migrated for some reason.

i will also add that making 7.5.1 a stand alone install was IMO
a bad way to do this.
i think that a complete uninstall of 7.4 and install of 7.5.1
would have been better, it has been a pain migrating settings.
though not to difficult but a pain none the less.
IMO
