It means that the workspace .RData is corrupted or that you have a
disk-reading problem on your system. It might be worth trying it again,
but if that fails there is no alternative that I know of to deleting
.RData (and your saved work is then lost).

R 1.3.1 is not very recent, and 1.4.x tries harder to ensure that the
saving process is safe. However, many of us do not rely on saved
workspaces to store information precisely because they are so vulnerable.
