Sketchup asked me to confirm my project with the same name which already existed. I had no option but to click yes as I could not get past that page. So when I went to my project page to opened up my project it was a new model and I had lost my project? When I tried to open the file a pink popup came up saying - THE FILE IS NOT ENABLED FOR VIEWER BASED ON THE PROJECT CONFIGURATION. TO ENABLE VIEWING CAPABILITY PLEASE CONNECT SUPPORT. The end result is SketchUp support recommended me to put in an enhancement request for SketchUp. See below the reply
Unfortunately the functionality to bring that file back is unavailable in the sketchup application. Due to files not being assimilated inside of Trimble connect we are going to be unable to bring that particular revision back due to the file not actually being stored in Connect. I would recommend putting in an enhancement request for SketchUp on this issue.
