I am experiencing two issues with PerfStudio.
1) I will be able to connect once on port 80 without a problem, but down the client and server, and then restarting the server yields an error dialog stating that it can't listen on port 80. I closed all other applications, yet the problem persists until I reboot my computer.
2) As a work-around I tried using the -port=<number> command-line option when launching the server, but I the DOS box quickly states "in option 'port': invalid option value". I tried ports 81 and 0180.
