Run the EQ2MAP updater as an admin.
As for it freezing... Launchpad.exe should be a completely different patcher than eq2.exe. Everquest2.exe is the actual game file (that skips the patcher). An old style patcher (like on the original game discs) is EQ2.exe and an install of that should not have a Launchpad.exe. If you have both in one install (in the same folder) that might be your issue unless their Station launcher does that for some reason. (I don't use the station launcher so I don't know the exact details of it, but to my knowledge it installs the launchpad in a completely separate folder).
