so Bochen and Zaza told me that it's your scanner.
at talonos.biomescanner.map.MapScanner.loadDataFile(MapScanner.java:95) go to C:\Users\(yourusername)\Appdata\Roaming\.technic\modpacks\blightfall\saves\(name of your saved world)
find the scanner.dat file inside the save folder, back it up (copy and paste it on desktop) then delete it. Edit. just to clarify: delete the original file, not the backup!
now try running the launcher and the game
it should generate a new file for you, but you must right-click the scanner in the Jaded again

the issue with this missing file should now be fixed: http://forums.technicpack.net/tracker/issue-3764-unable-to-download-akka-actor-211-233jar-with-my-own-new-mod-pack/?st=20

I've been wondering if we need to make another pinned thread stating where issues belong, so I can stop warning people here left and right.
but then this happens to be the only section that has way too many pinned ones, a second one will just be missed
 
and add to the fact that new people generally ignore pinned threads anyway. And the threads I close containing bug reports... those should've been the best hint* how the wind blows here...

Like plow said: post launcher issues on the launcher Tracker
 
edit.

AppDataRoaming.technicmodpackstest-111111111 looks like a custom pack to me. Add the link to the pack, Jammy. Otherwise nobody can help you

Nope, nobody knows. They are created at whim, sometimes by what the team feels the community lacks (in Hexxit's case it was a good RPG modpack with friends) and in AotBt it was requested by Generikb to make a modpack filled with crazyness and weirdness.

Please post in the Tracker. Platform Pagoda is for questions regarding custom modpacks
