I have recently played Voltz 1.0.9 and am now trying to update to Voltz 1.0.11. Every time I attempt to do this, the load will stop with "0% Backing up previous build to '2013-01-29-18.29.03-backup.zip..." and will not do anything after that. I have tried clearing the cache first, updating to 1.0.10, and re-installing the launcher. Nothing has worked. If anyone could help I would really appreciate it :)
