Can anyone tell me where to find legacy versions of Transmission for EX4100?

After updating to Transmission 1.07 on my EX4100, I get a ‘Connection Failed’ dialog. WD are telling me to ask the app developers, but all I can find is a forum, and I’m not getting any responses.

I’m pretty sure rolling back to 1.05 would sort the problem, but WD won’t/can’t supply me with it. Does anyone know where it might be available online? I’m guessing it’s a build specific to the EX4100, but I can’t find anything :frowning:

Please help - desperate!!

Aw you’re a star - thank-you!!
