I have the same problem with the regular eMule 0.45b
I solved the problem by editing the winapp.ini to:
[eMule]LangSecRef=3022Detect=HKCU\Software\eMuleDefault=TrueFileKey1=%ProgramFiles%\eMule\config|AC_SearchStrings.dat
So I removed the deletion of known.met (regular hash) & known2.met (AICH hash, if I'm not mistaken)
