NT65 import error on compiled assembly question

[SammyC]

HI

I have created a few custom indicators and compiled them into an assembly.
Trying to move these indicators to a second NT 65 computer to test install etc.
However, I get an import error.

Import Failed. The existing Ninjascript file "MyDynamicPivots" contains duplicate method names ......
What is interesting is that this indicator is no longer in my indicator folder or custom folder.
It had been deleted long ago.

Been reading in the forum that i may possibly have duplicate method name.
I followed the instructions to manually compile the indicators on the second computer and then to add the dll (compiled assembly) to the custom folder. I then shut down ninja and restart.
I opened one of the indicators i previously compiled; right clicked references and added the dll and tried to compile.

I get the following message for @ADL.cs file.
The Type 'NinjaTrader.Indicator.MyDynamicPivots' is defined in an assembly that is not referenced. You must add a reference to assembly 'DynPivotsWithSession, Version 1.0.0.1 Culture-neutral, publickeytoken=null'

I am not certain how to proceed.
MyDynamicPivots does not exist and either does DynPivotsWithSession as an assembly.

there are no changes i can see in @ADL.cs file and the indicators are no longer on my computer.
I also did a search within the .cs files in the inidcator folder to see if the inidcators were named differently... no trace of them anymore.
Did something not clean itself properly on the delete way back when?
Not certain how to proceed. Please advise....
Thank you advance
Sammy
