I use mt AO8 on an old xp box but use CCDSoft and TSXPro rather than maxim.
It seems to run fine with one exception. If I try to have the AO running and do a time series it will crash TSXPro after the first image. Individual images are fine. If I run it using my cheapy win7 lappy it runs with no problems.
The only thing to learn about its use is to run the calibration. You need a bright single star in the frame for it to calibrate on. Often this is difficult. The AO doesn't care which ccd you use to calibrate so what you do is swap to the imaging ccd and draw a box around a bright star with enough room for it to move with calibration. You then let the calibration occur with the subframe you have selected. Once this has occurred you can then change back to the guiding ccd for the AO to use. I often don't bother plugging the guider in and just use the AO. As long as your periodic error is low enough that the AO doesn't have to reach it's range this is ok. You can use the AO at low speed this way like a normal guider with 1 or 2 sec exposures on a quite dim star.
Cheers
