i cannot imagine that this has anything to do with your
software upgrade directly. it can be a side effect or
totally unrelated. possible reasons are the following:
- there is a hardware error on your hard drive carrying your
home directory and it has been mounted read-only.
- your (numerical) userid is different and thus you don't
really own your home directory and anything underneath
it anymore
- you launched VMD in a way that '/' has become its
current working directory, to which you have no write access.
can you generate other files? e.g. using "touch some_file.txt"
cheers,
axel.
