I haven't used my PS3 for ages mostly because my ext. HDD fell down and my BR Drive is dead too. (my PS3 only has 40GB)
So some time ago I removed the broken BR Drive and I could be wrong but I think Multiman didnt work since then anymore. Is it possible that Multiman needs a drive no matter if its f'd up or not? If not, what could be the reason for not starting anymore?
I've already uninstalled Multiman and installed the newest version.
