I have been working with the beta 4.0 version of Lightroom and this problem has only started occurring tonight. When I try to export edited files, an error message pops up, which begins with: An internal error has occurred Win32 API error 2... I have a screen shot of this. When I hit "ok" the error message goes away, and the file does end up where I'd like it, but its a lot smaller. What is happening? How can I fix this? I spent the last two hours trying to fix this. I uninstalled Lightroom and reinstalled it, to no avail.
