Weird BrawlBox v0.67b Error

[SemiPsycho]

Earlier today I was using BrawlBox v0.67b perfectly fine then now for some reason this message pops up:

Sorry but you are not allowed to view spoiler contents.

Does anybody know what this means? I tried downloading a new mscorlib.dll but it had no effect so I just replaced the new one with my old one. After that, I tried to download a new copy of BrawlBox v0.67b, and when I went to the download from Brawl Vault I was greeted with this message:

Sorry but you are not allowed to view spoiler contents.

Does anybody have a solution to this? I am using Google Chrome and I tested this with BrawlBox v0.67d, and it works still.
