Hi all,

I've have been playing with uCommerce 3.5 for some time and finally decided to upgrade to the newest version.

Downloaded the new version, sign into my umbraco backend.

I couldn't upgrade my 3.5 package, so I decided to install the 3.6 side by side with my 3.5 package. 

We I try to click the commerce icon the section is empty like mentionen in this question: http://our.umbraco.org/projects/website-utilities/ucommerce/ucommerce-support/44047-UCommerce-section-empty-after-install

I did query the listed table and found no extra values in the externalid column as mentioned.

Should I uninstall the 3.5 package? What will happen to my files and folders?

Should I uninstall the 3.6 package? What will happen to my files and folders?

I did try to read Sørens blog regarding upgrade, but it is dated back to 2010 - is every aspect of the blog still valid or is there a more recent upgrade guide / checklist?

On my shop I now get the following errors:

Error loading MacroEngine script (file: uCommerce/MiniBasket.cshtml)

Error loading MacroEngine script (file: uCommerce/LeftNavigation.cshtml)
