Wait, do you mean the Ignis Vortex or the Abyssal Temple dungeon?
If you talk about Abyssal Temple (the dungeon in Nemesis base), it's really hard. There is a big jump from previous dungeon to this one. I usually suggest to be level 47-49 to run it. Just whippers are a bit stronger and can already afford it in 45. And above all, Asura, the first boss, has a trick to destroy it, using the debuff given by his minions. Search on youtube some videos and guides about Abyssal Temple bosses. It's still hard in your level, anyway.
If you have problems in Ignis Vortex in level 43 (dungeon in Barbirion), you have something bad in your character, try to fix gears and biuld faster you can.
