As I mentioned in my other reply, time-out errors when trying to download from the C3DB are usually temporary, however, here it sounds like you’re having a different error. I’m not familiar with “clock not on right time” errors. Can you give more details, or maybe post a screenshot somewhere?
C3 CON Tools may be too new to run on Windows XP. I can’t say for sure because I haven’t tried running it on anything older than Windows 7. Make sure you have the proper dependencies installed, including .NET Framework 4 and Visual C++ 2010; details and download links can be found in the C3 CON Tools thread. If downloads for these dependencies are not available for Windows XP, then you will have to use a more recent version of Windows.
