Help "Error in opening zip file" error message when opening my new modpack.

[Emperor_Block]

Hello.  I just created a new private modpack on the Technic Platform called SwaggPak for just me, my brother, and my friends to play.  When I try to start it up, I get the error message "Error unzipping a file for the following pack: Swaggpak.  Error in opening zip file.  Please consult the modpack author."  I've googled all over for a solution and haven't found anything.  I have no idea what causes this issue so I have no idea how to fix it.  That's why I came here.  This is my very first modpack so I don't exactly have very much experience in this type of stuff.  I've tried all the solutions that I've found on the internet and tried them all to no avail.  To my knowledge, I've made sure that the DL link is in the correct format, that the modpack.jar fle is not a .ZIP or .RAR file, and that the modpack ZIP itself is a .ZIP rather than a .RAR (I use winrar so...yeah).  The only other potential problem I could think of is mod compatability, but I'm not sure if that causes the error I'm experiencing, since most if not all of the mods I'm using are part of other big packs (like Tekkit and CrazyCraft) that work flawlessly.  I'll post a download link at the bottom of this post so that you can make sure that it's in the correct format and so you can get the ZIP file.  Also, one more thing: all the posts I've seen anywhere tell everyone to check the console, so I did.  It just says this: [b#439] Analytics response [installModpack]: 200.  I assume that means that there were no errors as there was nothing else and the 200 means so.  Thank you for reading this and if you have any suggestions on how I can fix my problem then please respond ASAP.  Thank you.

• CodeChickenLib and ForgeMultipart belong in mods1.6.4 not the mods folder.
• Your version of Project Red has known problems. Update to the latest version.
• IDFix often just doesn't work as expected. In the case of your modpack it fails utterly. Run the pack once with IDFix in place and it will crash out. Disable IDFix and run again. The client will inform you that you have one block ID conflict which can easily be fixed. However, you'll have a large number of item ID conflicts which will need to be fixed.

As for why the pack isn't downloading you have not provided enough information. Please provide a link to your Technic pack page or the API URL.
