After loading COD1 & UNITED OFFENSIVE on Windows 7 Home Premium (upgrade from Windows XP Home), A message appeares when initiating "play": "buffer overrun," and I cannot proceed any farther. The message screen is headed - MICROSOFT VISUAL C++ RUNTIME LIBRARY. These games worked fine on Windows XP; and my system is unchanged except for Windows 7 upgrade. Any suggestions on how to overcome this problem?
