directx question

After reaedind desacrated hero's post I checked my own directx diagnostics and it is showing a file I can not locate thru run or file search.It is showing a yellow exclamation and the notes say the file is a beta version whic is unsupported and may cause problems.
The next note says i should reinstall directx and get the latest version.
I am running directx 8.1(latest version).I tried to reinstall and the file and message remain.
Is this anything I should be concerned about or any hints???
I am running:
win98se
celeron 500mhz
128mb ram

 

What's the file name in question, probably don't need to worry if everything is working properly

 

This is pasted from DirectX diagnostic page-
iac25_32.ax: 2.00.05.0051 English Beta Retail 2/13/1998 14:31:00 199680 bytes

DirectX Files Tab: The file iac25_32.ax is a beta version, which is unsupported and could cause problems.
You should reinstall DirectX to get the latest version.

 

Use system file checker to extract a new copy off the windows cd
this one is on win98se cab 22
Iac25_32 ax 198,656 4-23-1999 10:22:00p
