if someone knows where this has already been answered, i would appreciate a link. i have installed Logic RPC Pro (ver 5.1.3) on my WinXP machine. when i plug in the dongle, i get the error "Multiple XSKeys detected." i have two SI-24 boards installed. one came with Logic, the other with Sonar LE, thus i have two Emagic dongles. i do not know which dongle goes with which program. (i have loaded Logic on an older machine (Win2K w/ 2 GHz Pentium 4 and 1 Gig memory). on the Win2K machine, it runs with either of the dongles.) i have attempted to launch Logic with the following permutations: one dongle, the other dongle, both dongles, and neither dongle. without a dongle, i receive the appropriate message "Emagic XSKey not found." with either or both dongles, i receive the aforementioned "Multiple XSKeys detected" dialog. i have tried the dongle in various USB ports; each time the Device Manager is populated with only one instance of the XSKey. i have uninstalled the driver, re-inserted the dongle, and have been met with the same results. the machine in question is: Dell Optiplex GX280 Windows XP Professional ver. 2002 SP2 Pentium 4 (3.2 GHz) 1 Gig memory two (2) RPC-1's two (2) Roland SI-24 boards i'm not even certain what the correct question is, but generally speaking, what do i need to do to get Logic opened on my WinXP machine (patches, updates, hardware configuration, etc.)?
