This tip shows up with double quotes instead of single quotes.
I think it should read like this:
=(LEFT(A2,FIND(".",A2,FIND(".",A2,FIND(".",A2)+1)+1)))&(MID(A2,FIND(".",A2,FIND(".",A2,FIND(".",A2)+1)+1)+1,99)*2)

Another thought on this problem:
=REPLACE(A2,FIND("~",SUBSTITUTE(A2,".","~",3)),99,"." &MID(A2,FIND("~",SUBSTITUTE(A2,".","~",3))+1,99)*2)
