Edes mentioned on the chat that 1.03 was crashing their Centro, so here's a link to wifight.prc for edes or anyone else who'd like to roll back one version (only temporarily, I hope
)

This is NOT the most recent version, which at this time is 1.03. If 1.03 working for you there's no reason to downgrade.
