Last night when I ordered Realtracks Set 169, I got the same thing (error_invalid_order_data_response). I sent an e-mail to Sales and today I got a valid download link. The download was sucessful and I was so anxious to try it out but the one track I really wanted (John Jarvis, Piano Soloing) was missing. It was that track that made me order that particular set and I am so disappointed to not find it included as this writeup which I copied from the BAIB page says that it was:

RealTracks Set 169 : Killer Country Soloing Video Demo
One of the best things about Country Music is the killer solos played by killer musicians, and now you can have even more of that in Band-in-a-Box with RealTracks Set 169! This set features four different instruments soloing over four completely different country grooves, ranging from slow ballads to up-tempo train beat. There is a fiddle soloing over a medium even 8ths country groove, a slow swinging 12-8 piano soloist, an up-tempo train beat resonator guitar soloist and a mandolin soloing over a slow country even 8ths ballad. Each one of these is a real Nashville studio musician, and no matter what chord progression you enter into Band-in-a-Box, these killer players will be able to solo over it! The superior stretching features in Band-in-a-Box enable you to use these RealTracks over a wide tempo range, so there are countless combinations of bands when you combine these soloists with other RealTracks styles. Each one is also equipped with RealCharts, so not only do you get these fantastic musicians playing over your songs, you can see exactly what they're playing in notation, TAB, on the on-screen piano keyboard, or on the on-screen guitar fretboard! There's something for everyone in RealTracks Set 169!
Note: This RealTracks Set requires Band-in-a-Box 2011 for Windows or higher.
