Wp-admin Not Showing With XAMPP

I installed XAMPP and WordPress a couple days ago. I followed an instructional youtube vid and created a new database for it in phpMyAdmin.

Right after I installed it, everything worked fine, I could access the wp-admin page and log in to the wordpress interface.

After shutting my restarting my computer however, I can no longer access the admin area. I can view the front page of my site(on the localhost) but not the admin area(on the localhost)- I just get an “object not found” for it.

Any ideas on what’s wrong?

Thanks a million
