Looks like this may be caused by the "." in front of the folder path that you have specified for where the file is stored that you are downloading. The reason that nothing is happening after submitting the form is that the item being downloaded is not being found at the directory specified.
Try changing ".secure/MasterSW/RMPs/" to "secure/MasterSW/RMPs/" and make sure that the Test.pdf file is stored in that directory.
