My admin page has disappeared after add-on

[robbin21973]

Ok, I know there is a thread for Image Handler 2 and I have posted there but I may not find what I need there. I have unloaded this and my admin panel wont show up. I cannot log in, it's just blank. No error page. I now feel I did something I should not have done and have tried to correct it. I am not super familiar with many of the protocols but I have re-uploaded the admin and uploads from the original zencart download that I did about a week ago. I don't need the image handler and would rather have things back the way they were.

Anyone know where I should begin or what the issue might be? Thank you.
