There are two problems. You should treat them separately.
1) Account is not creating
2) Create Accounting in ending at warning.

In order to fix issue 1, you need to take a look at the Create Accounting output. See if you can view the output. If you are seeing XML output then run the Publisher program to view the output as I have done in the videos. The output will tell you what the problem is (with accounting). Most likely cause is GL period is not opened.

Keep in mind that validation does not mean that accounting will be created. Create accounting could have its own issues and only the Create Accounting program display errors in detail.

Alternative you can go to Tool->View Accounting for that transaction, and look at the error message there.

Why create accounting is ending at warning? You need to take a look at the full log file for that. There could be an XML publisher related bug that prevents publisher to launch automatically.
