Hi,

Can someone help me this error please?

Exception Details: System.NotSupportedException: The given path's format is not supported.

It's occuring when I try to upload a file using the uComponents URL Picker, but only in internet explorer 7 or 8.  No error occurs if I use internet explorer 9, the Firefox or Chrome.  Is it a setting in IE 7 or 8 or do I need to set something in the Umbraco web config?

My "requestLimits" node in the web config is set to 50 MB and the PDF and word files I'm trying to upload are only a few K in size.

<requestLimits maxAllowedContentLength="52428800"></requestLimits>

Here is the full error message:
