Here you go :
http://www.*********.com/file/t2welo
its send - space.

I've tried this 1 month ago and forgot but i think try both.
-
First put it in the system32 folder which is in Compuyer > Windows > system32
After that run the CMD as a administrator and type " Wzms.dll regsvr32 " and it should work
-
Put it in the maplestory folder.

thanks its fixed now i can go test it out and make online soon
