I had my application working till I update to the new version 6.2.3

I have neatupload control (upload control) on aspx page  hosted on a aspPageBox control

now when I click the upload button to upload my files i get the error below

when I set the validateRequest=false  it works fine but that is not the solution

please investigate thanks

Server Error in '/' Application.
A potentially dangerous Request.Form
value was detected from the client (vwg_pipeline="<ES LR="633674613522..."). 
Description:
Request Validation has detected a potentially dangerous client input value,
and processing of the request has been aborted.
This value may indicate an attempt to compromise the security of your application,
such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false
in the Page directive or in the configuration section. However,
it is strongly recommended that your application explicitly check all inputs in this case.
