I am guessing you where loading backups from the disk channel, then you installed some ios and now that give error. Error 001 should resolve with an updated cIOS and updated neogamma. These can be found in the softmod guides on this site. You can't load backups from the disk channel without a modchip or DARKCORP installed, installing the ios files would have broken any corp you had installed.
If you follow the guide below your issues should be resolved.
