PureTryOut

Is nobody able to help me with this? If someone is wondering what OpenJDK 7 is, it's sort of a Java port for Linux, it works easier then the official Java, but it's basiclly the same.

Launcher Version: 1.0.4.3 Operating System: Xubuntu 12.10 Java Version: OpenJDK 7 Antivirus Program: AVG Free 2012 for Ubuntu Description of Problem: I've uploaded a modpack.zip to Dropbox and Mediafire, but whatever I do, the launcher won't download the file. The zip has just the .minecraft directory in the root (bin with only the minecraft.jar/config/coremods/mods/resources). I put the Dropbox link into the launcher in the custom modpack, it downloads Vanilla, it seems like it is totally skipping my file, and then launches plain Vanilla. Any help...?
