Linux has Architect version 2.1.0 build 633, which a co-worker has been using. I am on windows and have the latest windows version 2.1.0 build 584. I cannot open a project he has created because it tells me to update to a later version. I can't do that unless there is some other way of getting the version I need then from Sencha's download page. does anyone have an idea why this is and how to get around the problem?
