I wish I had more info about the problem you are haveing, so I can replicate it on my server, I have windows 2003 server and the only problem I had from the TWGS was it didn't want to go on line then when i figured out I had to kill the telnet of the server I still could not get a connect to the TWGS then I had to go to the IP filters and set them to allow, when that didn't work I went and checked, and lo and behold microsoft had a second set of filters that were almost identical to the first set that were (if checked ) set to block, thats right they were set to do the opposite of the other filters when checked, I don't know if this helps you but that was the problem that I faced and had with my version, but afer a long session of adjustments it worked. If you can give more specific details of exactly what it is doing and I can research it and see if I can help. Also you might have a corupted download. Sometimes the download can get corupted while downloading, and this can cause all sort of errors, that happened with my SWATH, when I deleted it and redownloaded it, it worked. What I am saying is that sometimes anything can happen while downloading that can corupt a file being downloaded. Try uninstalling and deleting all instances of the TWGS from your server and get another copy downloaded from EISs beta site, making sure you have anything that can interfere with the download turned off when you download the TWGS again, my coruption came from my antivirus scanning the file while downloading it and the pause evidently caused it to not get all of what it needed to work, so I turned off Nortons for that download to get it complete, then I scanned the file after the download to be safe, then reinstalled it and it worked. try this and see if it helps and let me know, if you still get this error, then email me at this email and include the screenshot ot what it is doing. with a full description. And I will see if I can help you with it.
