Hi Gareth
Welcome to the fun world of the Vision
Not sure about you download, hmmm... are you linking it in using the Serial/USB adapter? I found that if I didn't install the software first before linking in the adapter my downloads failed. I think the software houses the correct driver for it somewhere on the CD.
I did have a download issue but that was to do with the data downloaded rather than the actual process, which Martin responded to. It might be of some interest.

Failing that, I'd give Nicky or Philippa a call
With regards to the timing issue, I'm still trying to get responses out of AP and have had a couple of other issues with the head and canister which have resulted in the assembly being re-machined. Both threads are:-

Hope it sort of helps
Cheers
