Grayed Out EA - Does not work

I recently programmed a very basic EA to test the relationship between risk/reward ratio and winning percentage (see below). The EA successfully compiles, but when I go to my MT4 terminal, the icon for the EA is greyed out and when I try to add it to a chart, I get the message "Cannot open file 'C:\Program Files\GFT_MT4 Powered by BT\experts\90% Wins.ex4' on the EURUSD,H4" in my journal.

I've already looked into this issue and the consensus is that a greyed out EA should work, but means there is no .mq4 file to go with the .ex4 file. Obviously in my case, this makes no sense, as I personally programmed the EA...and it doesn't load on the chart.

Can someone help me?
