SDK Manager Error: Unable to download the list of SDKs. Error code: 33554488

Hi

I am new to this and just trying to get a set up working. Unfortunately I am failing at the first step.

I have downloaded the SDK Manager zip and am trying to run it.

When I login I see this -

(if I try this on my home PC I see "Logged In as <username>"

I assume this is because I behind a proxy on my work PC!!

Is there anywhere I can configure the Manager or perhaps install the SDK without the Manager.

I can find no documentation of what this error actually means anywhere.

Cheers
