I haven't really had any problems other than you get the "This Project is not the Highest Priority" Message. I just ignore it & work will Download on the 2'nd or 3'rd try, I haven't run out of work yet & I'm running 7.0.42 & 7.0.44 on all 18 of my Box's ...
I usually run all my Projects at 100 Resource Share, so each Project is not the Highest but it's the same as the others so I get work for any Project that way ...
