I just did a search on "connector specific error" and this thread came up, so sorry if anyone gets annoyed that I am resurrecting an old thread.
Anyway, I am now downloading 4.2 SP2 on my Vista notebook, but the weird thing is that 4.3 worked fine on our two other Vista notebooks (same brands, one is the exact same model). I gues sit's the bugginess of 4.3 and the naughty nature of Vista. All of our other computers are XP and we didn't have any problems. Oh well.
