Can create Categories, but *** Can't create Products*** - Database error:

Please help.

Since I was having difficulty creating Products - the process fails with connection time out - Can't display the page -  I noticed that I can always create CATEGORIES at first, but not the products afterwards. -
I went back to version 1.1 - and was able to create 2 Categories and it failed after trying to create the second product.

I checked the database and saw the categories and the products there, and when I checked the code for both tables, it passed -
when I RAN the code,   I get ERROR messages:


Msg 2714, Level 16, State 6, Line 1
There is already an object named 'Nop_Category' in the database.
Msg 2714, Level 16, State 4, Line 1

Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.

and the other.
