Error 1335

I keep getting this error in regards to various .CAB files.
This program is Office 2003 Student edition. I recently had
to replace my WDC 160 gb HD and now I cannot get this to
install.

I have tried every tip o nthe Microsoft support centre, and
nothing works. Not memory allocation, not flatfoldering it
(copying files to HD and running setup from there), nothing.

I have heard that this may be a security issue. Is this
possible? This product was good for 3 installs it said,
and this would be my 4th. Is this the problem? If so, what
can I do?
