Thanks for your help. I have tried your solution too and first without sucess. The problem i found was a character mistake in the version so the generated filename of the modpack was not compatible with the technic laucher or Dropbox(I don't know which one). OT ON: Another question about Dropbox: My modpack gets more popular and i have read that dropbox has a data traffic limit of 20Gb/day. Is it true and if yes what will happen after the traffic limit is reached? OT OFF:
Hey, i have fixed this problem through this a few month ago and it worked fine. Since yesterday the problem was there again. I have done all the same changes as every update before but it won't work. :/ Please help me.
