HELP !

I am livid - I published a post earlier today and now it's gone - did anyone see it - any witnesses whatsoever??? Did anyone take it???? THis is what happened - I went in just now to edit and when I pressed save/publish I got this error message bX-c1muu5 and it said search this error on group blah blah and I did getting 00 hits so then I went back to look at my blog and the entire entry for Week 8 Google Docs is gone - not there - oh I see a light coloured message saying "Draft autosaved at 4:39 PM" maybe it isn't gone let's see - but how do I check this - well I'll publish this post now and then look for the missing entry bye
