[Xitami] Xitami Problem

[Adam M. Arents]

Hi,
I'm using the Stable Release 2.4d10 version of Xitami with Windows XP 
Professional.
The error message I get is this:
Xitami was suspended
Could not open HTTP port 80 - Protocol not known (No error).
I get this message whenever I open the xigui32 application, as well as 
whenever I click on the 'start' button in the xitami program itself.
I got the following info from a file called 'console' in the logs folder, 
if it helps at all:
2003/10/16 01:48:02: xilrwp: Could not open LRWP port 81
2003/10/16 01:48:02: Protocol not known

2003/10/16 01:48:02: smthttp: Protocol not known
2003/10/16 01:48:02: smthttp: No error
2003/10/16 01:48:02: smthttp: closing HTTP connections on port 80.
This problem also occurred with Current Release 2.5c0.
Any suggestions for how to fix this?
Thanks,
