Have you tried using MultiMC?

I have and i get the exact same issue. If i try any pack with ATlauncher it works just fine. So this seems to be limited to FTB Packs.

Bump. Still having this issue. Strange thing it went away for a couple of days and i was able to play and last night same issue occured.

Does 1.6.4 packs and older also fail? I see one issue in your log but I don't know why it happens:

[WARN] DownloadUtils.getStaticCreeperhostLinkOrBackup:122: Using backupLink for mcjsons/versions/1.7.10/1.7.10.json

Does your firewall block downloads? (It or something like that blocks tracker requests)
