Strategy tester reads EX4 but not MQL4 files

 
I downloaded the latest build of MT4 (509) and tried to use the strategy tester offline with tick data.. It reads the EAs that are EX4 files but does not seem to read the EAs which are MQL4 files. Is there something I am doing wrong?

You didn't compile the mq4 to a ex4
 
This never used to be a problem - the strategy tester ran all the MQL4s without having to compile them to EX4s.

LOL . . . nope, the mq4 is the source, the ex4 is the executable.
