Hi Alice,
In your case, asking here or e-mailing Eowyn would be correct.
(In general, you'd only need to e-mail Eowyn if you've already done the following: 1.) Check your spam folder. 2.) Look in your history of contributions or the changes to your profile ("Changes" tab on your profile). You should see where you uploaded the GEDCOM and be able to click on it.)
Your case is unusual. You're including the URL for your report page in your question. You've already found it. The problem is that your GEDCOMpare report is not linked from it as it should be.
Digging a little deeper ... I see that our system can't interpret your file. It crashed while trying to process it. It's lines like this that break it:
131. Susannah NORTH Martin was the
132. 4 CONC only
I'm sorry to say that we won't be able to run a report for you. My apologies.
Chris
