It seems that the EA INSTALLER doesn't install the files when the folder is on the root' c:\\metatrader\' . My sustem is windows XP SP3.
So I installed the two files manually( myfxbookea.ex4 in expert and myfxbookea.dll in the libraries folder) but it doesn't work and my results aren't updates( My login and password are ok..) Hope it can help to resolve problem.
Good luck Myfxbook ! and continue to provide us this great service..
