FInding troubleshoot in results: significant features

I have download the series matrix file from NCBI GEO dataset, and tried uploading the file to get differential genes with Log FC values and p.vaule. As I just have the control and tumor values for metadata under #CLASS statement. Hope I made my point clear. If anyone can give me the answer I would be grateful.
When I click significant features it gives me trouble shooting error. I don’t know what is the problem.
