Dear Themba
There was a change made in the exchange file between versions 1.1.0.5 to 1.1.1.11. The exchanges file must be rebuild. Development will need to schedule time for it. I do not have a release date yet.
I will release the update to you as soon as it is available.
The only work around until then will be to use 1.1.0.5. Note that the last TNG rates release for Swaziland was TNG Version 1.0.7.0 (02 February 2011). The rates for 1.1.0.5 and 1.1.1.11 is thus the same.
Our apologies for the inconvenience.
Belinda
