I've tried a couple of methods detailed in some other threads but in case I did them incorrectly I'd like to proceed as if I haven't.
How about telling us what you've tried so we don't waste time repeating ourselves? It's very hard to mess up finding a folder and deleting one file in it.
Sure, I copied the default_wallet file to another computer and tried to open with electrum on that machine. I also deleted the config file but that had no effect. Thanks for the response so far.
