Modpack not loading worlds

[astorstar]

Firstly, sorry if I have posted this in the wrong topic category, this is my first time using the Technic forums.

I have created a modpack which seems to work - no problems downloading it and there are no problems launching it. But it doesn't load any worlds, I will try to create a world and it says converting world, building terrain etc, and then It will go back to the main menu. I have tried things such as dedicating more ram to java and reinstalling the modpack.

Please reply if you know a fix

I tried launching it but received a warning that your Forge was too old. I updated it to 1614 and it launched, and I can create worlds.

I've actually fixed the pack now, guess somehow I managed to load the game with an outdated version of forge, thanks for replying anyway.
