Thank you Jeff for trying to help,
So here's the deal:
I've downloaded Illustrator and indesign on separate occasions with same
computer, same OS (mac-lion) these last 2 weeks, and had no problem
Since Friday I'm trying to download Ps Cs5... I restarted it today (since
you said on the forum it could be because of the destination-disk) to the
recommended default file, but ended up crossing the same warning; I've
joined it as attachement.
Maybe I didn't get something...please help me! Thanks!
