Error on Resume Submission Listing in Admin

I am getting several errors when I look at the right side of the resumes that have been submitted:

It says Export Submissions and then shows the errors below:
Warning: fopen(/home/tomnehl/public_html/wp-content/plugins/resume-submissions-job-postings/base-files/submission-entries.csv) [function.fopen]: failed to open stream: Permission denied in /home/tomnehl/public_html/wp-content/plugins/resume-submissions-job-postings/includes/functions.php on line 247

Please advise on how to fix this. Thank you.
