Here's my understanding....
I've had several CRASHES in my file.
Upon re-opening AC, the link to the TW HOST FILE has been damaged and can't be "fixed"..
The first option is to TRASH you local copy (with all elements you've added / edited since your last SEND) and simply re-log into the host file. Of course you will then have to RE-DO all the things that aren't there.
The other option is to work in DETACHED MODE...so now you can keep on working, but you can never update the TW HOST FILE (directly)...
I choose the 2nd option and IMMEDIATELY save a .PLN file. I usually rename it FILENAME + SAVED12202010....
Then I log back into the TW HOST FILE...Here I choose to DISCARD Changes and get back into the file as my old self. With the .PLN file open at the same time... I can copy paste new stuff into the TW File.
It just so happened that I was working on SCHEDULE FORMATTING... so I can't really copy and paste those over (although I can create a new SCHEDULE EXPORT and feed it in that way)..
And, if I edited objects, I have to flip a coin as to whether I re-edit in the revived TW File or try and pick out the edits and copy paste. Obviously with items such as walls that are associated with dimensions, the choice becomes critical...
