My project is crashing in the Build, but not in the Editor

I'm unsure of what the problem is, but I got the crashlog and opened it with VS2013, then the error report was the following: "The thread tried to read from or write to a virtual address for which it does not have the appropriate access."

I'm using some sockets stuff and all that. The scene has only one script and that's where the bug must come from. And I didn't foun anything on the forum that could help...

The link for the script: http://pastebin.com/E5qumRC2 This is the error log: http://pastebin.com/H8NejK3z And that's the output_log: http://pastebin.com/ay0pW4TW
