CMA on a Mac via Parallels

I need some advice/help in regards to the CMA. I recently bought a MAC (yes finally - and it rocks) and have been having some weird issues uploading content to some DL2's using the Mac version of the CMA. I have a total of 4 fixtures - on two of them the content will upload just fine, but then on the other 2 it acts like it is going to upload the content, but then the upload status bar goes away and none of the content loads.

I also downloaded the CMA on the Windows (parallels) side and could not get it to even see the fixtures. I tried refreshing the servers, etc., but it never saw them.

I know that on the Mac side of the CMA, you need to set the IP address and subnet manually, but do you also need to change these settings when running the CMA on the Windows side?

Any advice on these above issues would be appreciated!
