AKOUSTIK and ELEKRIK piano problems in ProTools

This is duplicate post I posted under AKOUSTIK...just in case.

I'm a NI newbee. Just purchased and updated KOMPLETE 5 for Mac.

All the Applications work perfectly as a stand-alone. But having technical difficulties using AKOUSTIK and Elektrik Piano as a plugin in ProTools 7.3.1.

Here's the 1st Problem.

After inserting AKOUSTIK as a plugin in ProTools, I load the first preset (does not matter which preset I start with) and I use the mouse to play a few notes on the virtual keyboard. Everything is good, no problems. BUT, as soon as I change to any other preset and use the mouse to play the virtual keyboard, there is no sound on the output. HELP!#1. The only way to use the plugin is to reinsert the Akoustik as a plugin and choose a preset...but the problem starts all over again. PLEASE HELP!


Here's the 2nd Problem...Sorta sounds like the same as the 1st problem:

After inserting Elektrik Piano as a plugin in ProTools, I load the first preset (again, does not matter which preset I start with) and use the mouse to play a few notes on the keyboard, everything is good, no problems.. BUT, as soon as I change to any other preset and use the mouse to play the keyboard, there is MASSIVE delay (about 5 seconds)
before I hear the audio. The only way to use the plugin is to reinsert Elektrik, choose a preset...but problem starts all over again. PLEASE HELP!
