Mike, you might be right, I will try this if I don't find any solution, but this is supposed to be the default setup, ie, the blog dir being inside the x-cart root directory. For example, the "Path to WordPress directory (relative to X-Cart directory, 'blog' is used by default)" setting in the "WordPress in X-Cart" configuration page refers to a subdirectory of the root. The same is supposed to be implied in the module installation instructions.
