“Failed to install SGD client” when accessing the secure global desktop from OS X

I am having an issue since I have upgraded to OS X Yosemite. I used to previously remotely access my work's Windows system from my Mac (OS X Mavericks). I had installed XQuartz and Java and was using Firefox as my browser. Since I upgraded to OS X 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 X Mavericks.
