Just installed EasyWorship 7 on a new computer; created and saved my second schedule for use this weekend. However, when I went to reopen it to make changes, i get the error pop-up "Invalid Zip local header signature" and the schedule fail to open. Help!

Invalid zip local header signature.

I did not see a solution to this problem.

I work on one computer and save to portable device and open at computer at Church.

Both are new and fully equipped.

It has been working but now my service was completely lost and last weeks was locked.

Do I have to do the service at the church?
