make sure that the streamauthhash entry in the config you are using is empty and not showing <enter_authhash_here> or anything else e.g. it should just be streamauthhash=
or remove the line completely.
if you deleted the old config then the original authhash should not be on your machine and will not have any effect whether i try to find and delete it now or wait for it to be automatically removed when it is deemed to be dead.
what errors were being reported in the log output?
also it might be easier if you sned me a pm with the contents of your config file -and if there are any 'include' statements then the contents of the included config files as well.
