FTB Unleashed missing gui

[Josaku]

As the titel says, my FTB Unleashed game is missing nearly every gui which makes the game unplayable ^^"
I have no clue what caused this because I could play normally until yesterday, but then the game suddenly crashed and the guis were gone.
I tried reinstalling th modpack but it diddn't work.

Here some pictures of how my Inventory and Chest-Inventory looks now:

Try it without the Texurepack and/or Optifine. Do you have a copy of the crash? Does it still crash? If it still does not appear with the Texturepack and/or Optifine removed could you upload a console log to pastebin.com to see if the log says anything about this. Click on the 'Paste my log to pastebin.com' button on the console. This will give you a link in the console that you link here. Look here for more info about the logs.

Using FTB without Optifine and/or Texturepack didn't help.
Here is the crash report, I hope this'l help finding the problem ^^"

This appears to be caused by the Open Audio Library nothing visual, though I'm no expert on the errors.

You said you tried reinstalling the mod pack. Did you force update? Try a complete reinstall of everything. Java, the launcher and mod pack by following this guide. Remember to backup your save(s) and configs.

Reinstalling the launcher helped and now everything is back to normal. Thanks alot, I don't think that I would have thought of this ever ^^"
