Has anyone else experienced this and has any ideas for me? Thanks very much for your help.I also ran into the same problem today. I have tried restarting, uninstalling and reinstalling and am running it from my admin account. So basically I have re-ran the newest version of the setup, tried running the emulator as normal and then connecting to it, however it just says 'now the companion will be updated, click OK to update' and nothing happens after that! I am stuck in an endless loop where this will not update. Hi all, sorry to keep this thread going! Appinventor has been working for me on RM CC4 for the past few weeks, but it seems they have decided to update the software (yesterday) and it won't work unless you update it!
