How to Resolve the popup error window when open AvePoint DocAve site in Windows 8.

Background

I used to meet an error popup windows when using AvePoint DocAve 6 in my Windows 8 OS. 

I copied the error, it said:

[TypeInitialization_Type]
Arguments: AvePoint.Common.IsolatedStorageHelper
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.1.30514.00&File=mscorlib.dll&Key=TypeInitialization_Type

   at AvePoint.Common.IsolatedStorageHelper.get_IsEnabled()
   at AvePoint.Gui.Login.LoginOnTo_SelectionChanged(Object sender, SelectionChangedEventArgs e)
   at System.Windows.Controls.Primitives.Selector.OnSelectionChanged(SelectionChangedEventArgs e)

It seems that AvePoint wraps the IsolatedStorage in its product. However, I donot want to contact with AvePoint, maybe I can resolve this issue by myself.

I almost search all document about the IsolatedStorage of Silverlight, unfortunately, nothing about this error.

Thinking

The issue happened on IE11, how about another Browser?

I downloaded a Chrome Browser into my production env. and then try it. 

Chrome's working well. 

Hmmm. It seems the error is caused by IE11. 

I changed our DocAve website certificate some days ago and the new certificate is not valid now,  that will be the reason? 

Resolved

I created a certificate from our private CA, and apply it onto DocAve Website in IIS. 

The Browser did not response me the certificate error again, and the issue was resolved.

Yes, the issue was resolved.

Why

I think Windows 8 (or IE?) is running under a stronger security policy than before (e.g. Windows 7/Vista), and the dangerous  sites are not allowed to write anything in User Cache now.

I changed the new certificate (the invalid one) back to DocAve Website, and add the DocAve Page into IE Trusted Site, the error popup was also disappeared.
