Installing Acumatica Demo and Service Unavailable 503 Error

I am trying to create a demo to mess around with so we can be as educated as possible before we start using Acumcatica live. I have downloaded the installer from this site and installed it according to the installation guide and I inserted the “Sales Demo” data to mess with. When I go to pull up the website it first says that it refused the connection and then I get a 503 Error. I open up my IIS manager and that application pool has stopped. I also look in the event viewer for a clue and I get 5 warnings.

The first 3 state the following:

“A process serving application pool 'Acumatica' suffered a fatal communication error with the Windows Process Activation Service. The process id was '24456'. The data field contains the error number.”

The second 2 state:

“A process serving application pool 'Acumatica' terminated unexpectedly. The process id was '23804'. The process exit code was '0xc0000005'.”

Then an error:

Application pool 'Acumatica' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

I am not sure what I did/doing wrong! If someone could please give me a little direction.

Thank you very much!
