Coaster Retrieval Help?

I was working on a coaster last night - saved it and everything/had begun working on the supports - I went to do dome more work on it this morning and when I clicked on its name in the folder, I was taken to an empty screen...my coaster has just vanished!

any ideas on getting back? Will XP run a "system restore" for a specific time? I have never had to do this, so am not sure. Or is there any other way that might work?

thanks ahead of time,

dhh

Correct me if i'm wrong, but when you restore your comp. to a previous date, it will require you to re register screammachines. (there also might be a bug that when you type in your information, it will say reg key in use). There is a chance its still on your comp, just look for it, if not, then forget about it
