Client refusing to open

[civesclade]

Ill make this simple. Every single time i open the launcher to start minecraft with hexxit, it just does not open. It does its usual little file check but it always stops and then just gives up. The file that it always stops at is version.json it just sits at 0% then gives up. The only way i have found to fix this so far, is delete the hexxit mod set and have it redownload it again.. And as you can probably imagine, it gets rather FRUSTRATING to have to completely delete everything whenever i want to play. Anyone wanna lend me a hand please?

I took a quick skim through the logs and found this

[WARNING] File version.json not found in C:\Users\(name)\AppData\Roaming\.technic\modpacks\hexxit\bin\modpack.jar
