It's a known issues FileUpload and UpdatePanel

First thing you might wanna try, is checking the authentication to the associated folders, whether you have proper rights to access to those folder.

Sometimes it doesn't work on the first click but the after. You might want to try this code

(in the code behind, set the id for the button in Page_Load
btnFileUpload.ID = "btUpload";

Hope this helps
