Unable to load bigWig files

I have just upgraded IGB to version 9.0.2 (windows 10).
I cannot upload bigWig files which did load in the previous version.
The message is "Unable to load data set for this file. Would you like to remve this file...".
Have tested several bigWig files, all with the same response.
I was able to load BED file.
Restarted the PC and restarted the application a couple of times.
Thank you,
