MoP Update but cant access to update?

Started 07/25/2025 - MoP Classic needs and update. Click update. " We are having problem transferring data please check your internet connection " provides and unhelpful link.

I can log into BNET - chat with friends but can not update. Wont let me scan and repair, uninstall to reinstall says same thing.

I have x2 MoP updates in Que and cant do anything looking for assistance

Update* 07/26/2025 - This is also for all my wow versions.

Install RevoUninstaller program (its free, usefull and safe)

Remove your WoW, and battlenet app.
Important: remove all the trash what battlenet leave behind (its very badly coded program, it leaves many trash, and after reinstall it uses all the earlier trash settings, etc)

After u completely removed all the things, reinstall battlenet app, then WoW.

If u r behind a router, then it would be useful to set the blizzard/wow port forwards to your computer.
