Login page theme issue

Hi,

Im having problem with using a custom css for the login page in vCloud Director. The css does not apply after upload -> apply ->restart browser.

I have followed these instructions (Import a custom login page style sheet into vCloud Director 5.1) : http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1026050

The version we are using is 5.1.1.868405

Any ideas?
