After perusing PMDG's website, I considered buying subject product. But does everything that works in v5.0 still work the same in v5.1? Is this product good to go for v5.1 with the hotfix? Is it asking too much for devs to specify what versions it will work with, like maybe say... "v5.0 inc. 5.1, also 5.1 with hotfix." Does no one remember 5.0 products that had to have a patch for 5.1? I am assuming that PMDG is promising that it will work with all versions of 5.0, and I don't have to be concerned about the no refund policy. Right? But what about the "v4.4+" language? So, this works in everything from v3.4 on up to 5.1?
