Error message for network analysis

Hi!

I keep getting an error during step 2 in Create the PPI network from the edge table and prepare it for data annotation. I have the matrix of the protein-protein interactions open and am trying to transform it into the "Network collection" data structure by selecting Network → From matrix → Basic → From matrix and choosing protein1 and protein2 as 'Source' and 'Target', and checking the Network is directed option. When I click OK, I get the following error message:
