Problems after new installation (Runtime workbench not working as expected)

Question

Hello
We have just finished installing new ECC & Netweaver in our company.
On PI side, I created a sample file (Payload) and did IR and ID configuration
and saw the payload getting picked up from the source directory and getting
posted in the target directory successfully.
However, when I went to Runtime Workbench and clicked on the Adapter and
File adapter to see the messages, I dont see anything. It is just blank.
However, when I click on Display it shows integration server and 4 items under it. 4th item is Adapter Engine which has a RED button next to it, indicating there is some problem.
When I click on the Adapter button to see the list of adapters, i see again a red button next JPR. However, File doesn't show any error message. But when I double click on File adapter, instead of showing successful messages, it shows a blank screen as if no file has been transmitted.
Also down at the bottom of the Runtime Work Bench Screen
Self-Tast Status and
Are Communication Channels without errors
also show a Red buttons next to it.
By double clicking on 'Are communication Channels without errors - Details", I get the following error message:
1 communication channels have an error status0 communication channels inactive0 communication channels not providing any status information0 adapters logging communication-channel-independent processing errors .
This is a fresh new install and any feedback on this will be greatly appreciated.
Thanks
