Blogger vs WordPress Blog

I am trying to export my blog. The first 2 times I tried this, I was able to (seemingly) - but then I could not open the .zip file on my computer. Unfortunately I deleted these files from my computer thinking they were invalid. Now, I can't even export - I keep getting an error message. I've read past threads but they are not offering any insight for me. I'm wondering if you can export and send me the file by email on file with our account. This seems the timeliest way to resolve this and would be MUCH appreciated! Thanks so much for your time

The blog I need help with is collagenblu.wordpress.com.
