pc companion and update service are not working...help?

[#1]

I have a sony xperia X10.  I want to update my phone because I think it will run better, so I have downloaded the PC companion, and it will not work for me.  It keeps running me in a circle.  it will go from the part where you have to turn your phone off  and plug it in to the computer, then it will go to the part where you have to mount it.  After you mount it goes back to the part where you have to turn your phone off and connect it to the computer.

I found a link for the update service...http://www.sonymobile.com/gb/tools/update-service/  in other disscussion, so I downloaded that and tried it, but it is doing the same thing as the companion. 

All I want to do is update my phone, but it won't let me   Does anyone have anything else I could try?  I would really appreciate the help.
