Failed to Publish Packages

Hi,

any reason now why it always failed to publish packages? the error message always says "Verification of file signature failed for file..."

I've checked few solution from the past year and mostly about the file sze. however the EminentWare.Utilities.WSUSThirdPartyUpdatesHelper from this link seems no longer working. 

Any new update?
