GREAT service - but this version has a "document path invalid" error. :( – Adobe Acrobat Sign Review

I've come to rely on this service for 1) having a recognizable and trustworthy name (Adobe) as well as 2) being reasonably free (up to 5 signatures per month) for a photographer who only occasionally needs this kind of service with this level of sophistication. I'm not sure why, but I'm currently trying to access a document that's waiting for my signature and I'm getting a "document path invalid" error when I attempt to open it. :( I'll try completing from the browser instead, but this is a MAJOR fail when it's the foundation of what this app is for!!!!!!
