The IBM Building and The 13 Floor?

"THE IBM building in Brisbane’s CBD is now back in the hands of the owner after a fire broke out in the ceiling of the 13th floor today.
Fire investigators conducted atmospheric testing in the building due to the excessive amount of smoke.
Special equipment, known as a MultiRAE, was used to declare the scene safe.
Most of the personnel and equipment had left the scene by 4pm.
Edward St has also reopened after being partially closed after the fire broke out around 12pm.

Investigators will return to the site in the morning."
IBM Brisbane building catches fire
Hmm ... The 13th Floor, hey?
That rings a bell somewhere;-)

 "Computer scientist Hannon Fuller has discovered something extremely important. 
He's about to tell the discovery to his colleague, Douglas Hall, but knowing someone is after him, the old man leaves a letter in the computer generated parallel world his company has created  
(which looks like the 30's with seemingly real people with real emotions). 
Fuller is murdered in our real world the same night, and his colleague is suspected. 
Douglas discovers a bloody shirt in his bathroom and he cannot recall what he was doing the night Fuller was murdered. 
He logs into the system in order to find the letter, but has to confront the unexpected. 
The truth is harsher than he could ever imagine..."

UPDATE: 1st November, 2015
I watched The 13th Floor  for the first time last night (October 31st).
Not as good as I hoped it would be, but it was worth a watch ... just.
