Withdrawing paper from a conference after presentation due to error Please refer to the following link for details. I am planning to send an e-mail to the conference chairs regarding my withdrawal. 
I wanted to seek help from the experts in the community for drafting the e-mail since I believe that it should be very carefully crafted since it is going to cause inconvenience to the conference committee(even though I haven't submitted the copyright form and the paperwork hasn't started yet).

What are the details that I should include in my e-mail? Do I need to be specific about the error or just write that I've discovered an error in the paper(considering the fact that I will continue to work on the paper and submit it to a journal)? Also, what possible responses should I expect from them?
Any help would be highly appreciated. I am having problems sleeping since the day I've discovered the error and cannot concentrate on my work. I just want to make the fact explicit and move ahead.
You are overthinking it. A simple note is all you really need. "The paper needs to be withdrawn as we have found a serious error that we don't believe can be corrected in time for the conference." 

This won't have been the first time that a paper has been withdrawn. It is a matter of scheduling sessions for the program committee but some of the members are probably familiar with that. There may be some scrambling, however, if proceedings have already gone to press. But they should have copyrights in order before that happens. If they don't, then it is their problem, not yours. 

No, you don't need to detail the error, just that it exists and that you don't have a ready fix. If the conference is part of a continuing series you may have it ready by next year (or whenever).
