Commented Unassigned: Not able to import certificate [184]

I have not been able to import my code signing certificate, keep getting "Check the file" message. It imports fine when I use the MMC Certificate process so the file is ok. Where is the program looking to find the certificate and what is it checking for to validate the import?
Comments: try this : - Start WPP - Go to Tools -> Settings -> Server tab - Check the option "Ignore Code-Siging Certificate validation errors" - Try to import the certificate once again
