After a successfull AxCMS.net installation you see a red error message over every page in MS and LS saying "Could not load the license XML. Visit AxCMS.net website to get your free license!":
Either you do not have a valid license file or the path to the license file in web.config (key GlobalLicenseFile) is not set correctly.
A) If you don't have a license file, request it on AxCMS.net website.
B) If you just downloaded a free AxCMS.net, you should have recieved a localhost-license automatically - check you emails.
C) Ensure the path under GlobalLicenseFile in web.config (both MS and LS) points to the localtion (absolute) where you stored the license file.
Licensing of AxCMS.net is described in details in Installation Guide (see below)
