Be sure (100%) that you copied your ex4 and/or mq4 in the right folder as follows ...

Files >>> Open Data Folder >>> MQL4 >>> Experts 

Then restart the MetaTrader platform.

Im sure about that the source file copied in location u told , for example i run my expert on time 2014/02/11 until 2015/02/11 in main computer that i programmed by that expert run and do what that need to do but in another computer tester just go until 2014/12/28 then stop and finish !
