Does anyone have a copy of WinAIRR 4?

I was wondering if anyone had a copy of WinAIRR (Anechoic and In-Room Response for Windows 95/NT) software from Old Colony that they could email me a copy of. I am not looking to pirate the software, but only want to try it before I think about purchasing it. Yes, Old Colony has a demo available, but $5.00 + Shipping for a demo is a bit rediculous. The software is only as big as one floppy, so I would really appreciate it if anyone would help me with this.
Thanks in advance!
