Trouble Connecting

Hi, Idgo211 here, a learner on beta.redstone-server.info. Starting yesterday, August 13, I started having issues connecting. My wifi had been very slow and laggy, but I wasn't the only one (Ecconia was also lagging from bad wifi) so I didn't think much of it. Soon after, I tried to connect, it worked fine for about 10 seconds, and my game crashed. It was that Java SE Binary platform crash message. The only mods I have are Single Player Commands on Forge. Every time since then, my game crashes with the same message when I try to get on this server. All other servers are working fine. I suspect there might be an issue with one of the scripts. I am running Windows 10 but this isn't W10 minecraft. I haven't had any troub;es until now. Please look into this vecause I love this server. Also please inform me as soon as you believe you have it fixed. Thank you!
