No audio output when I dropping samples into Logic Pro 9

[Polacy]

Hey guys, this seems to be my last shot - no one doesn't seem to be able to help me out...

So I been using a sample pack lately and it's been working perfectly until the last two days.
Suddenly when I drag them into my projects it doesn't come any output.
Neither the CPU or the db-meter doesn't respond, the waveform becomes weird like none of these drums are not even supposed to look like this!

I attached a picture of how a 808 looks like.

So here's some points I've answered a couple of times in my other posts (other forums+groups)

1. I have tried to re-download the package and it still doesn't respond correctly (must be a bug in Logic?)
2. The samples still WORK in my other projects
3. No I haven't moved it to a MIDI-region
4. Read about using solo-button 's' a couple of times - doesn't work
5. MIDI works as it should do
6. Other samples packages works as it should do, except this one!
So there must be a setting that I have missed?

7. Universal Track Mode is Enabled
8. I/O Buffer Size is set to 128

I'm running Logic Pro 9 in 64-bit with 32-bit bridge and been doing it in a year.


Appreciate any kind of help here...

Does bit rates of project and sample match?

Hey mate,

Both has 44 100 sample rate.

Well that was my only clue, because think it happened to me with 32 bit samples before.

If you are on 10.6.8 by any chance, 9.1.5 is most recommended one for best performance, so maybe downgrade to it or even do clean OS and Logic install now.
