Formatted Wii system memory and can't do nothing

Here's how it happened:

Booted System Menu 4.3U wad

Formatted Wii memory in software

Errors

Deleted virtual System Memory inside Dolphin folder

"Unknown entry type 0 in SYSCONF (@499)!" error when booting prog

Clicked ok

Dolphin ctrlpanel came up

A bajillion "Trying to read from invalid SYSCONF" errors

Game list appears

I try to boot the game

Same bajillion trying to read invalid sysconf errors

Program crashes

Reinstalled a bazillion times

Same errors

Possibly the config files are the problem?
Any way how to delete the config file?
