Error in generating plot using plotFingerprint

I am doing an analysis of previously published ChIP-seq data for a bioinformatics class that I am taking. When I try to use the plotFingerprint tool to compare the IP strength between two samples (treatment/control) it is giving me the following message:
“An error occurred with this dataset:
format png database mm10. Job failed.”
I’m not sure how to correct this issue so if anyone has any suggestions that would be great.
