For some reason the technic launcher is not allowing me to download any modpacks. I have tried all modpacks and all that appears is a 0% in the loading bar which quickly disappears. I have tried restarting the launcher, resetting the modpacks, restarting my computer and nothing seems to work...

Has anyone else had this issue previously? There appears to be folders created within the directory but nothing else (no files).

Any help is greatly appreciated.

This is the error I get:

java.util.zip.ZipException: error in opening zip file

Your best bet is to head to the specific file in whatever Users folder it installed to (My Technic Launcher, for some reason, installs a different mod-pack to every user, instead of keeping to only one name), and delete the specific modpack in the modpacks folder. If that doesn't work, try deleting the modpack in the Assets folder. And if that doesn't work, you may just have to delete the contents of the .technic folder entirely. It's the only way I've been able to manually reset my Technic packs.

I'm not a Technic Pack coder / member, so my advice should probably only be taken as a last resort, especially the last one if you don't mind losing your saves to all modpacks. If you're still having trouble, I suggest asking on the official Technic forums. They'll probably have better advice than my own.
