easy populate drive me to admin page

For my websie, everything is fresh, and I upload easypopulate 1.3.9 with zencart 1.3.9, I can see easy populate is under my tool section, nothing showed wrong on the page, however whenever I click upload or download , it will redirection me out to the admin page, I need log in again, hope you can help me. :no::(

I also have this problem.

I have just installed Easy Populate 4.0.17 - Beta 12-24-2011 onto a fresh install of zencart 1.5.0.

Seemed to install ok.

When I click on complete products export, I'm redirected to the admin login page, where I have to log in again. Same thing happens when I try to upload a file. The export has worked fine, it's just that I'm logged out everytime I do anything using EP4.

Site is not live.

I am having this same issue. I am using Zencart 1.5 and every time it try to import the csv file it just redirects me to the admin login page.. so i am still unable to import my products. I have already tried to re install the ez populate and came up with the same results. Does anyone know why this might be happening?

Do any of you have error logs generated when trying. To perform one of the problem actions? (Zc version less than or equal to 1.5.0 in cache folder, 1.5.1 and above in logs folder)

Also I thought current EP4 was 4.0.22.
