I bought the Mbox 2 Pro about 6 months ago and it came with the bundle package. I got The Protools LE software and a bunch of plugins. I installed in my Dell laptop with Windows XP. And it simply wasn't working. So then I set it all up on my Desktop computer which is also equipped with Windows XP. This worked for a little while. But now, every time I try to record, it tells me to reduce or increase the buffer size or something. Apparently it has something to do with the CPU usage. So. Basically, I just want to record. Either fix the problem on one of my current computers, or look into buying one with more compatibility. I would rather have a PC, but I am willing to explore both options. If you know how to correct any of this mess, help me out!
