Sorry for the confusion.
I reupload all files from
https://mathhelpboards.com/vbulletin...ers-22030.html and reinstall product.
Now, work fine.
Strange because, is the same version that I was have.
Only think that, a few days ago I migrate my site to another server...in the migration some corrupt file...? Is the only that I think.
Continue with the problem with ibproarcade, but this product, now, work fine.
Sorrys.
