Minecraft CurseForge

hiii, the problem is solved. But for people who run into the same problem.

Well I was planning on playing playing craft of the titans ( first time )

but my curse won't let me start the modpack.

I tried to start different modpacks as well but it just won't start, I don't even get a warning like "unable to start game" 

I click on the play button, the picture of the modpack loads.. and that's it!

Yesterday everything was still just fine.

Anyone any idea what it could be?

I have reinstalled the curse client, that didn't solve the problem either. 

I had Java 8, i know that can give problems as well, so i deleted that one and downloaded java 7, and that didn't help either. 

And now i'm out of options I can think of...

Oké I have fixed the problem. I don't know what the exact problem was but what I did is : 

Delete Curse client -> Download Curse client

Delete Java 8 -> download java 7

Restart my computer.

Fixed.

Tnx for your time!
