I managed to fix this issue by disabling an external firewall set up by my router. If anyone else is experiencing similar problems, then try it and see if it works.

I've now managed to fix this issue by disabling my router's firewall. Thanks to those who suggested it might be an external problem as I've been struggling with this same problem for weeks. Anyone else on this thread who is suffering as the OP is, try it!

I have had this same exact problem, with apparently few other people experiencing the same issues or being able to provide an explanation. Launcher Version: 1.0.4.3 Operating System: Win Vista x64 Java Version: 7u10 x64 Antivirus Program: MSE, Technic Launcher allowed through firewall and without AV. Description of Problem: I've had a variety of problems with java as of late, minecraft could only run using a .jar file and previous java runtimes had become corrupt. I assumed that this had messed up the technic launcher as well, seeing as these problems started around the same time; but now I'm not so sure. I've reloaded vista, formatting my computer bar the windows.old folder, downloaded 7u10 x64 and then downloaded the technic launcher again only to be met with the same problems. "Upon launching, the launcher is blank (there are boxes, they're all blank, other than the tumblr feed area which shows the "tumblr is down" error)." The only way of telling which modpack i've chosen is (after a long loading time) the window is renamed with the mod pack eg. " Technic Launcher - 1.0.4.3 - (Tekkit) Multiple times I have tried to login with my account (same as my username) and it did nothing, however after the format it did show up with my skin (however still did not login). What I see is as shown here: "After blindly choosing (any) modpack, typing in user/pass and hitting login, I get update failed instantly. I've tried reinstalling technic, java (multiple times)." Error Messages: " Login failed... Oh Noes! Our Tumblr Feed is Down! Would you like to run in offline mode? Update failed!
