Update from lasts versions.

Hello, i have an installation of WBB4 bêta 5.

Actually the last version is bêta9.

I try to install bêta 6, bêta7 and bêta8 before the last bêta9 version, but when i try it, i have this error :

It's the same problem if it select bêta6, or other version ..

Hello,

the problem is that even if i select bêta 6 ( actual version of my board is bêta 5 ) in the drop down menu, it detects that I selected bêta 9.

Ok, thanks
