This is highly cursed (2 WLM's running at the same time with different servers)

Escargot MSN Server
3

u need to use this wlm 7.5 zip (u will need english messenger dll, coz i got it in portuguese ._.)
u can extract it in normal place where its installed, AFTER WLM 2009 is installed

then install WLM 2009 and patch it like normal

Then u will install MSN Polygamy in WLM 2009 (Escargot has the download)

Then run MSN 7.5, then WLM 2009, and boom
