Hello Reader, I have a Scanmagic 1200cp scanner. Everything has been fine til yesterday when it started scanning ok and then stopped with the message...Mustui has caused an error in KERNEL32.DLL. Mustui will now close. If you continue to experience problems, try restarting your computer...Well I did continue to have problems and yes I did try restarting my computer and yes I`m still having the same problem, so any ideas please. If you have, plain and simple instructions please! Thank you........Penelope.
