you mean that it still times out? crashes mysql? maybe the table (tc_countries) is corrupt? try doing a repair.
select up into 2 selects and throw the results of the first into arrays. Didn't want to do it like that, but it's gonna be quicker now.
if at first you don't succeed... hack ;-) <snip> try removing the ORDER BY Clause:
SELECT b.fldName,
       b.fldEmail,
       b.fldCountryCode,
       d.fldCode as FCode,
       b.fldMobile,
       a.fldTime as Time,
       c.fldUsername
FROM tblSubscribersChoices a LEFT JOIN tblUser c ON c.fldClientID = a.fldChoice LEFT JOIN tblSubscribers b ON b.fldID = a.fldClientID LEFT JOIN tc_countries d ON d.fldCode = b.fldCountryCode ORDER BY c.fldUsername ASC
OR.... SELECT b.fldName,
        b.fldEmail,
        b.fldCountryCode,
        d.fldCode as FCode,
        b.fldMobile,
        a.fldTime as Time,
        c.fldUsername as Username
FROM tblSubscribersChoices a LEFT JOIN tblUser c ON c.fldClientID = a.fldChoice LEFT JOIN tblSubscribers b ON b.fldID = a.fldClientID LEFT JOIN tc_countries d ON d.fldCode = b.fldCountryCode ORDER BY Username ASC
and if that works but doesn't give you repeat records try adding the DISTINCT keyword after SELECT. <snip>
