Pixelspark 4.2.7.1

Hey, I'm new to these forums, but, not that much with Aternos. The reason I'm here is because whenever I try to open my 1.8.9 Pixelspark server (4.2.7.1), It shows "Loading" and then "Starting", but the starting lasts forever until the server just closes, and Pixelspark worked before the update, can someone help me?

I started the server before the update just fine, but then I saw it was 4.2.7.1 and got excited and went to sleep, the following morning, I got onto my computer to see what's in the new update, on the server, but it wouldn't open. Is it because Aternos cant handle that much data or?...

Start your server and open the server console. When asked for it, in the server console type in /fml confirm to proceed with the starting process. Download and save your world before, though.

I cant join my server D:
