DNN 7.0.6 Upgrading Smith Cart from 5.65 to 5.68. I have an existing maintenance license.
the only changes I made to the 5.65 install was styling changes.

Installation Wizard Upgrade message states successful install
Loading the page containing the BuyNow module throws an error
----A critical error has occurred. Object reference not set to an instance of an object.----

BuyNow Module page has no admin menu. Using the module settings button I can get to the Smith Cart Settings page. All settings appear to be correct. There is a new required page titled Vendor Page. I added a vendor page to the site and added the vendor module. Received a notification to purchase a license. Should this happen since I have a maintenance agreement? New license won't help since I can not get to the SC Admin menu.

I deleted the templates from the portals/0/smithcart/templates folder and tried a repair install. Received the same error.

The event viewer error message follows: any recommendations would be appreciated.

i have encountered an additional issues on the product listing page. If I use more than two tabs in the description section the listing page throws an error. This was repeated on a test portal using my skin plus the gravity skin. it also occurred on my live site. I did a clean install on the live site and the error was repeatable. I also received the error described above on the product detail page.

Kevin, As you will note in my first posting I deleted the templates. I did a completed clean install, deleted all modules, deleted all database tables and stored procedures, deleted all folders from the Desktop Modules, deleted the templates from the portal/o/ directory, cleared the cache and restarted the application. Then installed the smith cart module. I did this on two systems, twice on one of them. the failures persist.

Okay, I will try that.

Issue Resolved! Thanks for your assistance Kevin
