WD EX4100 v1.07 'Connection Failed' :(

[Bersgard]

Can anyone help me? I updated Transmission on my WD EX4100 from v.1.05 to v.107, and now I can't connect to it - getting 'Connection Failed' dialog. I'm not much good with 'back end' stuff (oo-er!) so would really just like to roll back to the earlier version that worked. Western Digital are being absolutely useless, and can't/won't provide me with any help at all.

Does anybody know what I can do? Thanks in advance
