NMRView Can not see the spectra

[paquin@xxxxxx]

Hello,
I have downloaded and installed the version 7_0_14 of NMRViewj on Fedora
Core 6. The software runs with a recent Java version (jdk1.6).
But when i try to open and draw a spectra folder (with the recommended nv
extension), no spectra appears. However the "Manage Datasets" says the
dataset is open and the right chemical shifts are also displayed. I've yet
used the option "Open and Draw Dataset" from the Datasets. Could please
help me to sort this problem?
Thanks.
Raphael.
