I kept getting Error Code 54 on my submitted returns the past 2 days...

It says to update by software

Attempt # 1 - Clicked on "Update software"  Downloaded...Re-ran review diagnostics on the return....submitted it ..same error code 54

Attempt # 2 - Waited for "automatic software update" was downloaded...re-ran diagnostics on the return...submitted it...same error code 54

Attempt # 3 - Went to Update... hit " refresh Updates"  downloaded....Re-ran review diagnostics on the return...submitted it...same error code 54

Attempt # 4 Went to Update...hit  " download new products for all federal and states checked"   ...downloaded ...  re-ran review diagnostics ....submitted it...finally got return accepted

Apparently there was a problem with Update processing  using

a- Update installed products

b - Update automatically 

c - Update refresh

I basically had to treat all products as "new product"  download and install before it accepted the return...
