I hate to bring up dead in the water fish but thought it wouldn't be appropriate to post a new thread on the same problem.
I am having the same black screen issue when I try to unzip and then rezip a coccoonjs export. Even if I make no changes. I am using the built in Zip and I have Windows 7 Home premium.
Should i download Winzip?
What could I be doing wrong?
I am highlighting all the files - right clicking and choosing send to zip file.
