M-Powered 7.0 + FW1814 MTC timeout?

[alexkbd]

Hi All - would appreciate any thoughts regarding the following:

Upon setting up the click plugin on an aux track and starting the transport - a few "clicks" are audible as expected and then silence (input signal on the plugin also stops illuminating) though transport remains playing. Number of clicks seem to be fairly random - sometimes one single click, sometimes up to two bars will sound... any instruments also behave in the same way - a short burst of sound followed by silence.

Am using latest 1814 drivers (5.10.0.5036) and have tried CS1 update.

System is:
Asus A8N-E
AMD 4400+ X2
2GHz Ram

Love to hear from you!!
