Total "Melt Down" in LS

What I had feared could happen, has. I've had a total melt down in a LS project. I was editing some field names on the sql server, but did refresh the connection. Any pointers on debugging this would be appreciated!

Sunday, July 15, 2012 1:26 AMI had a friend whos LightSwitch took a dive. I had him create a new table (doesn't matter just any table) and that fixed everything. It appears that when you create a new table LightSwitch will recreate everything and that can sometimes fix it when it is hosed up.

You won't be able to do any of the things suggested above, until your lsml file is fixed.
Look in the Errors pane & either try to fix the problems listed (double-clicking the error will take you to the line in the lsml file), or post them here.

That is correct. My suggestion would only work if you were getting the red X's when you are able to run the application.You won't be able to do any of the things suggested above, until your lsml file is fixed.

After I reread th original error I realized that you are correct. My suggestion will not work until the error in the .lsml file is fixed first.

Then answer was to simply restore from a backup. I had less than an hour of work into it so wasn't all that bad. This also taught me ( again ) a valuable lesson, backup as often has you'd care to re-do the work. The next time I'll also run WinMerge against the live and backup project directories. This could be real of real value debugging what exactly went wrong.
When developing in LS, I will be backing up hourly.
Thanks
