I've seen this particular error message before, and to my knowledge, it has been fixed. I believe it occurred on Windows machines running Windows 95 or 98 only.

Hence, it sounds to me like you still have a previous version of CSDS on your system. Before running CSDS again, run the Windows File Explorer, right click on the csds.exe file, select 'Properties' and locate the version. It should be 1.11.xxxx. If it isn't, you are running the wrong file. If it is, then double-click on the csds.exe file to run it. If it runs fine, then your desktop link or Windows Start menu link refers to another version of CSDS.
