so the serious problems are so serious as to suggest me not to buy the download version

Read these two Topics in the 757 Captain - General forum:

Was 4.5 really tested?
ILS and HDG Problems with 4.5

This will show you the seriousness of the problems in v4.5. You can decide for yourself if you do, or don't, buy it now. If you buy it now, you get a free update to v4.6, but you may not enjoy using it until v4.6 is released.

the 4.6 has an aproximate release date?

I am not a member of the Captain Sim team, so I really don't know how when it will be released. I could guess, but who knows how close to right I would be.

As the saying goes, "It will be ready when it is ready".
