Did you manage to get it working?

If not then make sure that you're on cgminer 3.7.2.  Those versions that you mentioned are old.

What do you mean by "doesn't start mining" ?  More details would help.

Also try without the SDK, uninstall both the SDK and the Catalyst drivers and try to reinstall just the Catalyst.  Apparently you don't need the SDK anymore, and I have heard reports of failures with it installed.

Also try one card at a time.
