Off topic, because I happened to see the posts about windows/linux: mac? Yeah works well with some things and looks nice. Otherwise linux all the way (just because I'm an Apple fanboi)
I've owned several Macs. Dating from a '91 G3 Power Mac and older to a 2009 Intel Core 2 MacBook. And I have to say they're the worst pieces of trash I've ever used. In fact I got so frustrated with OS X that I smashed the MacBook on the ground. If you're on Windows, go to "C:\Users\<username>\Documents\SKCraft Launcher\instances\Alice 1.6\minecraft\crash-reports" and find the latest report and copy and paste it here with "[ spoiler ]" at the beginning and "[ / spoiler ]" at the end (without the spaces inside) so it doesn't spam the thread. If you don't have Windows then you'll have to ask someone else where the new directory is or find it on your own.
Not too bad. Most indie games are available and some AAA studios are also beginning to develop for Linux. Here's my current list on Steam: Spoiler
There are no crash reports shown! I paste that in, and it says "No items match your search." I searched and searched, nothing!
It seems that this modpack is not able to be run on a 32 bit operating system due to the limitations of 32 bit java. I will do more testing myself but that will mean that I have to setup a 32bit os on my spare pc first.
But do you have a 64-bit JVM? You can get one here if you need it: https://www.java.com/en/download/manual.jsp Don't forget to update your 32-bit java as well if not done automatically, as a new update was released a few days ago. Seeing as how you use linux I assume you might use OpenJDK. If you use OpenJDK I'd strongly suggest switching to Sun/Oracle Java, as Minecraft is coded for Oracle's Java and a lot of mods are incompatible with OpenJDK.
32-bit and I have no problems, which leads to the conclusion that it's either not Java but Windows that makes problems, or that 32-bit Java only makes problems on Windows but not on Linux. Either that or I'm incredibly lucky. We already had an extensive discussion on this, but I am still using OpenJDK, 32-bit even, and I currently do not have a single problem. Everything works flawlessly.
I recommend that you install the 64bit version of Java. if you cannot do that or don't feel comfortable doing it I would be more than happy to assist you over teamspeak! Just drop me a forum pm
32-bit Java does tend to occasionally crash Minecraft on 64-bit Windows. However it works fine for 32-bit Windows to my knowledge. As was discussed before, Mojang themselves indicate that Minecraft should be run on Oracle's JVM. And I've seen at least one player experience a major reduction of crashes by migrating from OpenJDK to Oracle Java SE.
I downloaded the 64bit JVM from the link you provided drift. I am givet the following: The game is running. Please wait.

How much ram do you have allocated and how much do you have on your system? Just want to check even though I doubt it's the problem. Although I hate to blame SK after all the work he's done, it seems like a problem with the launcher as far as I can tell. What's your operating system btw?
Looks like you're going to have to wait for SK or someone from the MPT to help you. All I can suggest right now is to try clearing your java cache.
