This is important imformation for every PC Top Spin player so I therefore urge you to read this.
To play online on Gamespy you will have to download and install the patch that fixed the online problems that existed before. If you do not have this patch it's almost impossible to play a normal match online without running into problems!
The link where you can download the patch is http://www.gamershell.com/download_7854.shtml .
When you've downloaded it make sure you extract to a different folder than the Top Spin game folder. Name the new folder 'TS Patch' for example. That's where the files will be extracted to.
When you've extracted the files to the folder you'll see there are 2 of them. Now open the general game folder (where you've installed Top Spin).
First of all you take the .exe file (with the Top Spin logo) from the Patch folder and you drag it into the general game folder. It will now ask you to replace the file. Click yes.
Then there's the onlinepart.dll file. You'll notice that within the general game folder there are more folders. Open the OnlinePart folder. Finally, drag the OnlinePart.dll file from the Patch folder into this folder. It will once again ask you to replace the file. Press yes again.
That's it! You should now be able to play on Gamespy without any problems (if your opponent has the patch installed as well of course).
