Nope, those files need to be manually saved when we are in that current patch. No one archives them anywhere.
You might be in luck in this case.
I have the files from last patch saved in a zip so i could do my last shoutcast.
Download the zip, put all those files in that zip into your EIRRarchives folder and you will go back a patch.
Save your current files tho so you dont have to autoupdate again.
