I'm awaiting a long (and very slow) transfer right now (hence checking my
email), I will try the suggested driver, probably tomorrow now, and get
back to you/the group.

You have clearly put in a fair chunk of effort to bring me that information

return the favour, but in the mean time, I hope "Thank You" will suffice :)
