GC Won't Load

[Steve Juniper]

I recently installed the latest GC in a new Vista PC desktop, using same 
data file as always. Worked fine several times but this morning when I 
tried to load it it stopped at the first opening GC window (which was 
visible as always) and the "tips" window, which was black. Smaller 
window appeared with the msg on top "Windows - no disk" Lower was the 
msg "Exception processing message parameters 0Xc0000013....." What on 
earth can I do about this (my line command skills are almost non-existent)?

I load GC from shortcut icon on desktop. Data file is in a "Finances" 
folder, also on desktop. Both worked fine before.

Thank you very much, in advance.
