A note for you arch, if someone gets an error about a corrupted file, it is ALWAYS because of a download error. Occasionally, downloads just break, and assume they are done, which will give an error if you try to use it. It's more common on slow connections, and using an inbrowser download manager, such as firefox's has a higher chance of breaking than if you use a download manager such as the firefox plugin, downloadthemall, or an external download manager like 'free download manager' (honestly, everyone needs FPM, its the best! Makes sense, with all the AWARDS its won!).
Either way, corrupted files always just need a redownload. Worst case scenario is the file was uploaded to the web server corrupted, in which case you would need to contact the webmaster an have them reupload it.
Please put a [SOLVED] in the title for this topic (edit your first post and change the title there).
