When i run the program (dsa.vi example and it's developped vi), the led of trigger timeout always on, this never happened before although i variate the scan rate and frame size. (LabView 6.1 in Win98, DAQpad 1200). This problem happened after uninstall the LV 6.1 and installing LV 5.1 then uninstall it then back install the LV 6.1 with install the network.
