Accessing the secure gobal desktop from OS mac - getting erroe “Failed to install SGD client”

I am having an issue since i have upgraded to OS Yosemite.

I used to previously remotely access my works Windows system from my Mac (OS maverick). I had installed xquartz and java and was using firefox as my browser.

Since i upgraded to OS yosemite with both JAVA and xquartz installed i can access the secure global desktop site and can also enter my log in details.

The screen then moves to "loading" and then freezes with a final message that states "Failed to install SGD client".

Any ideas as to what i am doing wrong...never got that message with OS Mavericks.

Thanks
