Sadly, I haven't been able to connect to the master server at all in the past 2 or 3 days. Can any1 help me? ill provide any info about my computer if and when I need to.

Before you do that, you should look around this forum, this thread in particular might contain the answer you need.

First read this thread.

already did it...

The thread we pointed you to suggests few tests you can do. Did you do them? What were the results?

What AV you have?, some AV have a Firewall build inside, and maybe the AV block ( For any odd reason ) your lfs conection.

this happens to when you reinstall LFS or update the "Exe" of the game, or change the location of the exe. so the AV with the FW, block automaticaly the connection request

This happens with nod32 and Eset small security.
