If Avast is blocking it, I'd like to confirm. It doesn't do that to me, and one user specifically disabled it.
lord buson I tried that after running a game byond doesn't crash the game just never launches... Its so bizarre. Like bypassed an error by avast stupid ass only to run into a fk you from byond. ( only a pun I know byond loves me maybe its a troll from my life ).
N293, if you follow the steps outlined above and can get me data, I can get this fixed. Once you get that data, go ahead and downgrade.
Naruto293, I'd recommend to install BYOND 509.1300 and again disable all {your antivirus program} shields or defenses, and then run BYOND. BYOND 509.1310+ will most likely crash if you have a module of your computer blocking it.

Important Note: If you wish to help by providing the error within a debugger first, do it as well, because it would help Lummox JR find the error/s.
Trust me I really would like to help find out the error my favorite game is coming back. However I am not really good with byond's codes and things of that nature. I'll try downloading the older version first and go from there.
I don't know how to download older versions, please help.
It's just a set of steps to follow:

1) Download and install the Windows debugging tools from Microsoft.

2) Start WinDbg and then start a game.

3) Once Dream Seeker is stuck, go to WinDbg and attach it to dreamseeker.exe.

4) In the window that comes up, type ~* to get a list of threads. Look for one that says dreamseeker.exe, byondcore.dll, or byondwin.dll. It's probably thread 0.

5) Now type ~0s to switch to that thread, replacing the 0 with another thread number if you got something besides 0 in the last step.

6) Type k to get a stack trace.

7) Copy the entire contents of the window and use pastebin or something similar to share it with me. Or you can even post the contents in this thread; wrap it in <dm> or <pre> tags.
When downloading windows debugging tools will it be named windows 8.1 drivers kit? I currently am on windows 8.1 and am downloading Wondows Driver Kit Update 8.1 ( Just making sure this is the debugging tools ).

Is there a video tutorial? because I'm trying but its not really working that well.

Have you tried disabling your antivirus?
I actually had to disable my antivirus to attach the debugger. It wouldnt connect at first. after doing that I took these steps. If your asking can I play a game with antivirus disabled? I am saying no with antivirus on my byond hub crashes. With it disabled the game I launched never starts. My mouse shows loading icon for maybe 10 - 20 secs and then nothing.
What crash info do you get from the Windows event viewer when it crashes? That's data I can definitely use.

I suspect your antivirus is in fact causing the hang, as that's been the case for a number of other people.
Ok so uninstall it? or turn off all antivirus completely? because I suspect that my antivirus was still running after disableing it.
I would just temporarily turn off your antivirus; no need to uninstall.
it should have the ability to exclude processes from scanning somewhere in it's settings... try that and add byond.exe and dreamseeker.exe in program files (x86)\byond
