Hi!
It seems that the distribution to agents in the nightly builds is not working currently. We are currently in the final phases of developing loadUI 2.0 (which has been in development for 8 months), in which agent communication has been rewritten from loadUI 1.5 (among a lot of other new features and fixes). Therefore, we don't have the time to try to fix the nightly builds for 1.5.
LoadUI 2.0 stable will be released in 2 months (loadUI 2.0 Beta1 in 1 month). In the meantime, we recommend you to try loadUI 1.5 stable (not nightly). It should work better.
Sorry about this
