Just my luck-my mate asked me to install his new usb printer-he had no usb drivers on his system-so i downloaded a program called oemusb from windrivers,put this onto his computer and restarted but now i have a message at startup saying the following files are missing or the date is wrong:-(rough recollection of message)

vmm.vxd
shell.vxd
vtd.vxd
vxdldr.vxd
vpicd.vxd
or vwin32.vxd

the pc won't boot windows-not even in safe mode !?!

his system is using a 200mhz pentium pro with 64mb ram and 2gb hd.

any help would be appreciated as he now thinks i've knackered his pc !?!?!?!
