The title of this post is the error message I've been getting when I try to open an Ecco Pro file in Win XP under Parallels ever since I upgraded to build 3214 a few minutes ago. This is supremely important file for me (fortunately I have backed it up). The file still appears to be right there, with 1.1 MB of data. But it can no longer be opened with Ecco, and it can no longer be copied onto my Mac OS 10.4.10 desktop. What on earth is going on? Thanks for any help.
