My WoW doesn't start anymore

I have download Run & Play from this page https://www.apollo-wow.com/how-to-connect/
I have set realmlist correctly and i played until 10 minuts ago. I installed some addons.

I play on Apollo 2, my character name is Warbike (level 80)

I just get this error once i start game: "wow cannot stream required archive data. please check the network connection".
I already deleted cache and WTF, i named those as "CacheOld and WTFOld"
I tried to downlaod again the launcher but it doesn't even start anymore!!!
My internet connection is working fine, i can connect to apollo web site correctly too...
I tried to removed addons too but it didn't solve the issue(npc scan and npc scan.overlay + cooldown addon).
I tried to replace WoW.mfil with the one on "how to connect" web site page of apollo.

How can i solve this problem? I hope you will reply as soon as possible.

tried just replacing new file, didn`t work, so I deleted all files/re-installed (download while playing mod) and THEN swapped files, and i managed to login no probs.
only downside is that now it`s a tad bit laggy since it`s downloading while i`m playing but it`s working,so it`s good enough for me

For the people having some sort of "Cannot stream required archive data. Please check the network connection." Or their equivalent from your language. There's a fix guide.

Close your game, ALT+F4 it, or End Task of any WoW.exe in your Task Manager.
1. Make a backup of your current WoW.mfil, located in
/Main Folder/.
2. Make sure you have the
Read-only option deactivated in your /Main Folder/ folder properties.
3. Download this WoW.mfil: Fixed WoW.mfil
4. Replace the WoW.mfil from your
/Main Folder/ with the one downloaded above.
5. Open the game, and try to enter.

6. If you can enter to the game, you can activate the Read-only option in your /Main Folder/ folder properties, or maintain it deactivated.

If you still have problems to open the client, it's maybe from the next issue:

- You are running a client with other language than English (GB).

You maybe need to re-download the mini-client, or wait on the English (GB) until downloads to 100% if you want to change the client's language.

Have a nice day,
