I just tried it and everything works fine in V3.1.1. If the problem persists, pls provide the exact error message.
The error message is
A block that appears
KVS availabilty tool
A big red X
Error Retreiving Fare Rules
with an OK block to click
When you click OK, the block goes away, but nothing else displays
I did BOS-ATL R/T
pos SG highlighted the fare line
right mouse click picked view fare rules
Tried other routings and also tried AA
and picked the first block (the DL fare rule)
