Install Error....

When I try to install the pro version of the component I get the following error:

Awocoupon Pro - A coupon enhancement for Virtuemart
Database Tables Installation: Successful
Core (Required): Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Add Shipping fields to Coupon Form: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Order Number in Checkout: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Call AwoCoupon on Selection of Shipping: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Display Correct Shipping in Basket: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Show Shipping Discount in Coupon Display field 1: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Show Shipping Discount in Coupon Display field 2: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE
Retrieve Calculated Shipping from AwoCoupon: Unsuccessful - FILE DOES NOT EXIST OR IS NOT WRITABLE

The Component works enough for me to setup a coupon, but it doesn't work when I try to use the coupon code.


Thanks for the help,
Dan.

Sorry I read back though the instructions and did the "Installation Check" and made all of those files 777. Then checked the boxes and installed them.
