I've got a fully-patched version of WinXP Home onto which I have tried to install and use eigenD, with no luck. I've tried versions 1.2.14-stable and 1.3.13-unstable. I uninstalled 1.2.14-stable before trying the unstable release.
My system does recognize my Pico and upon the first plugin, the devices drivers were found and installed with a little help from me. When I plug the Pico into a port, I can confirm it is found as an "Eigenlabs Instrument/
EigenHarp Pico".
However, in both versions, once I fire up eigenD the process goes to 99% cpu usage and I never get any lights on my Pico.
I know the Pico works correctly b/c I've also got a Mac that I use with it. I very much need to move over to my old WinXP Home machine so my wife can use the Mac and I don't have to keep sleeping on the couch.
Help is greatly appreciated.
