Hi Tracy and welcome to Digicamhelp!
Sorry to hear about the transfer problems you're experiencing with your camera.
Do you have Windows 98 or Windows 98SE? If you have W98 only, seems the driver will not work with it. According to the specs for the camera, the USB transfers only work with the following Windows operating systems:
Windows ME
Windows XP
Windows 2000
Windows 98 SE
If you have W98 SE, trying uninstalling and reinstalling the driver. This is not always a straightforward task so if you're not technically inclined, get someone to help you who is, or try again to contact Vivitar support.
Have you considered buying a memory card reader? I believe your camera uses Secure Digital Memory cards so get one that accepts SD.
The reader will probably also require a driver, so make sure it is compatible with your operating system. Since you have an older computer, the USB ports may be USB 1, not the newer USB 2. Make sure the reader is compatible or backwards compatible USB 1 compatible.
Most of this information is listed on the outside packaging.
Let us know how it goes.
