It might help to know what operating system you're using. But as a first step I'd check for any software updates that might be available for your system.
Considering that the camera is probably at least 15 years old you're likely to find that there's little or no recent support or updates, from either Canon or Windows or Apple for the most recent operating systems. Though I'd guess that most computers would still recognize is as a USB device when plugged in and let you transfer files using the file explorer feature.
All things considered, the simplest fix would be to purchase a USB card reader to fit your CF card and transfer files that way.
