One for the gurus out there. I've just moved house and re-connected the PC. I've inserted the memory stick I always use (2 GB) but the PC isn't reading it no matter which port I put it in. It isn't coming up as an external drive option when I click on 'open file'. Any ideas? There is no obvious damage to the stick and the files I'm trying to open are Excel and Word. Thanks in anticipation, Frustrated P-T!
