Did you use Java SEVEN's newest version, or the overaall newest Java version? He specifically says Java SEVEN, not java EIGHT.
In other words: https://java.com/en/download/manual_java7.jsp

If a developer goes through the trouble of pointing out a specific version of java you should use it.

It appears from those error logs that its looking for Java 7.71 class files, and they do not exist.

After reading how to update the spatial drives I am still lost and am afraid of updating because of corruptions. Can someone please help me understand what I am supposed to be looking for and how I do it. Thanks!
 
Alright. Travel Anchors aren't working. I can get to the Spatial IO location from other Travel Anchors, but I cannot seems to go from the Spatial IO port to anywhere else. The closest I can get to is the Reflection Pool, but if I look at it so I would be able to teleport to it, it disappears. The one directly above the Spatial IO location is obstructed. This is a massive roadblock, and it means I cannot experience the incandescent gleam it shone from the beginning.

Whelp, after updating to the most recent version of the modpack, I'm having the same issue lol. Not sure what could be causing it, have you tried downgrading modpack version to see if it's version specific?

While I may be wrong, it seems that the problem is that it can't find the Forge tweaker...

Alright, I tried deleting Material Energy^4 (the folder), and then reinstalling it, and the issue is still going on.
 
I had to resort to explosives to get the metallurgy blocks in the lava under the rotunda. I just haven't done enough mining with my new Ardite pickaxe to level it up. I believe I mentioned in ME3 that I hate mods like Metallurgy, & adding Iguana Tweaks to it is just plain mean. At least I have my tinkers tools this time.

Yeah, I've been stumped on how to get the Vulcanite for ages... As well as Yellorium. I have no idea what pick to use, but I'll try an ardite pick. Problem is that I have absolutely no aluminum... Wtf?

There is aluminium in the "Miners Delight" Underground, there should be some Aluminium Ore Berry Bushes

Hmm, yeah that's what I was afraid of. Guess I just wasn't focused on getting the bushes (only had 4) and overlooked that I never found any ore. Is there more ore down there, too, or just the bushes?
 
Wish me Luck, I probably just broke my save though :3 I hope updating the pack again fixes the template

I just dragged all the template Files since I just started and just kept the Inclusion Chamber, all other things I replaced, I hope
 
So far:
Broke The Modpack
Reinstalled
Hoping for the Best xD



EDIT: I fixed it. If the spatial drives dont work, then rip

I saw 1 of the youtubers find adamantine parts in a chest somewhere in the earlier rooms, but I don't remember where & I haven't gone back to clear the rooms yet. If you missed that, there are 2 other metallurgy metal blocks in the nether sphere that have to be alloyed together to make a pick good enough to get the vulcanite.

I just used a Terrain Smasher, wrench and chest. I did the same for the Yellorite, Quartz. Just make sure you don't wrench it to face the chest.

Also, which dimensions should we update? I've done up to the Nethersphere^4. Have there been changes to those maps?
