Currently dowloading data?

Ive dowloaded the 28Gb version of Mop 5.4.8.

When im playing it says Currently dowloading Data?? but i downloaded the full 28gb version?

People in the past have mentioned that waiting 15 or so minutes with the client open fixes the issue. Go ahead and try that.

It might be checking data, downloading very specific data of certain zones. I know that Cataclysm one was not entirely complete, so it might be the case with this one as well; but there is enough data to use WoD customizations if you wanted to and the Data that can be missing is minimal.
