Readycloud app for iPhone

Hi. I wonder if anyone can please help me. I can no longer access password-protected files when using the readycloud app for iphone - I get a "decryption failed" error message each time. I can still access other documents from the app and I can access all docs (ie, including password-protected) by going online to readycloud.netgear.com. I signed out from the app and deleted/reinstalled it but that made no difference. Regards. Jonathan
