An error has occurred while decompressing one of the encrypted files in your Zip file. This error most commonly occurs for one of two reasons: either the password is incorrect or the Zip file is damaged.
The first step is to verify that you are using the correct password and try to extract the file(s) again (perhaps you simply typed the password incorrectly).
If the error recurs, the Zip file is probably damaged. If you obtained the Zip file from an online source such as the Internet or AOL, it is likely that the file was damaged during the download process; in most cases, you will be able to correct the problem by simply downloading the file again. Otherwise, you will need to obtain a new copy of the Zip file from your original source.
If you can't obtain a new copy of the Zip file, you may be able to extract many of the files by selecting them individually for extraction (rather than extracting all). It is possible that only one or a few files are damaged.
