I recall a similar problem when I was with Telerate. At that time was still the Cruz brothers and the version was TS4.0. They were not ready for international use with data from different part of the world (read time-zone). So we always had problem with 24-hour FX data.
I suspected this problem I am having with some symbols may be a time-zone issue so on another computer I set time zone to UTC (GMT). DAX and UKZ loads. The other still no.
Update:
UTC + 1 and the problem with the stated symbols return.
No problem. I will work around.
