I have Windows 98 SE on my PC I purchased a 125Mb memory stick and the store wrote the software for it onto a CD. When I tried to load it onto my PC the CD disc was empty so I downloaded what I thought was the correct driver/software for the memory stick from the internet. It didn't work. I went back to the shop and he did this time load the software onto a CD and I subsequently loaded it onto my PC. I have deleted the files I downloaded from the internet. When I plug the memory stick into my PC USB port the screen just freezes until I remove the stick. The mouse curser can move around but nothing else happens. The USB works OK when I plug my digital camera in. Any idea what has gone wrong?
