EXPORT TAB LEADS TO "PAGE NOT FOUND"

HI
I AM USING OC V 1.5.5.1 WITH THE FREE EXPORT/IMPORT TOOL AND IT WAS WORKING JUST FINE UNTIL YESTERDAY.
WHEN I GO TO EXPORT MY FILES AND CLICK THE EXPORT TAB IT TAKES ABOUT 30SECONDS THEN GOES TO PAGE NOT FOUND EVERYTHING ELSE IN MY ADMIN AND WEBSITE WORKS JUST FINE. MY HOSTING WITH GODADDY SAYS NO ERRORS ARE FOUND AND IN MY ERROR LOG IN OPENCART ADMIN NO ERRORS ARE LISTED. THE FILE IS NOT THAT LARGE THEY(GODADDY) SAID IT SHOULD NOT TIME OUT BECAUSE I HAVE THE MAXIMUM TIME ALLOWED. I HAVE SEEN A FEW SIMILAR POST AND GOOGLED BUT WITHOUT A RESOLUTION. DOES ANYONE HAVE ANY INPUT?

THANKS

mywebsite/admin/index.php?route=tool/export/download&token=5bef47368e49e9f59b011f53313e837f it says "safari can't open the page because the server unexpectedly dropped the connection....."
In internet explorer it just says "'oops page not found"

anybody?

I am having the similar problem from past two days. Everything was working fine till 12th May. Suddenly admin login stopped working.

When I try to login with my credentials in admin

Here is error message I get in Safari

Safari can’t open the page “http://www.nojhanjhat.in/admin/index.ph ... 55943f0625” because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again.

Here is error message I get in Chrome

The connection to http://www.nojhanjhat.in was interrupted.

The front end is still working fine but I am not able to log into admin page.

Please help !!
