I hadn't run Seti for a month, and I just tried today and got Error Code 100. I went to the website and checked and couldn't find that errror on the list of errors compiled by safalra.com. I reinstalled Seti but still got the error. I noticed that it was still trying to send old results, so I deleted the results file and all was fixed. I just wanted to let you all know how I fixed this in case any of you happen to get this same error. (Sorry if this is all common knowledge already and I just missed it somewhere.)
