The string of
Error converting '<>' to float: set to 0.0
and so forth are normal behaviour when reading Bruker data.
Does the spectrum load at all (and just have duff referencing) or does analysis hang?

Subject: Re: Problem opening 3D NOESY processed with TopSpin4
Hello,
Do you have the 2.4.2 updates? Bruker changed how they specified the TopSpin version at some point after 2.4.2 was released, and this meant a patch had to be made to take that into account. (I think it was from TopSpin version 3.5, or so, I hope they haven’t changed it again in TopSpin 4!)
