Hey,
Make sure you complete the update that your computer has done. Once you have done so, make sure you restart your computer.
If that doesn't work, try compatibility troubleshooter. To do this, right-click on Yuri's Revenge CnCNet, click on properties, click on Compatibility, and then find 'Run Compatibility troubleshooter'.
One of these two steps fixed my problem, not sure which.
Also, when do I get to start posting without the moderators holding my hands on each post?
