Beams don’t seem to be Beams

Hello

This is my fisrs posting here, so hello everybody :D.
I’m stucked on Dante’s Inferno mission, having problems taking off the “umbilical connections” between the station and the cruiser. I cannot target the “umbilical” in any way. I have tried with the Image Module, placing myself about 600 metres away from the station and I cannot subtarget any part of the station. Well, I supossed it was not a problem because I would get down the “umbilicals” anyway, but I cannot.

I have realised that my Cutting Beam (and also the Comms Laser and Minning Laser) works in a very strange way.
First, they dont seem to be real “beams” because they are getting on and off very fast (about 3 times per second, or even faster) so I have not a continuos beam, I have a “flashing” one.
Second, they don’t have the ranges that are told in the Encyclopedia. I switch to the 3rd person point of view and the Beams (all of them) end really near of the starting point, about 200 metres (not 2.5 kilometers!) of my ship, so I cannot cut anything with this low range ray [xx(].

Have somebody seen something similar? I cannot take down this mission!

Thanks [|)]
