XenServer and XenCenter Console broken and not displaying graphs performance stats correctly

I've been banging my head against a problem for awhile, the XenCenter management app for XenServer stopped showing performance stats and graphs awhile ago. The Console screen also was blank so I only could SSH into the machine from putty if I wanted to admin anything... Hmm

Today I discovered the answer, there is a cache folder on the Windows machine that the XenCenter app is installed on and this cache of data needs to be purged!! So to remove the subfolder that is located in %AppData%\Citrix\XenCenterMain.exe_Url_xxxxxxxxxxxxxxxx.
If you remove the other folder as well, you will have to readd your Server hostname and password to the client. No biggie. Hope this helps someone else!
