Okay so our firm is sort of new to being on an Autodesk subscription. We are running MEP 2012 and have recently downloaded and installed MEP 2013 but have been reluctant to use it. What I'm wondering is if other people have had any issues with the program being buggy. A couple of things have kept us from using it so far 1) it's the first of a new file format (2013) which makes me nervous and 2) we have been having one user who has had performance issues with 2012 and I'm concerned its going to magnify with this newer version and 3) it just came out (thinking that it's like you should never buy the latest and greatest features on a car because they'll be the first items to break) Any feedback would be great. Thanks
