Member not found. Error

[DewayneH]

A few days ago Curtis Waguespack supplied me with a rule (Big Thanks Again). I tested the rule in many scenarios on several data sets to verify it's functionality. It was flawless. Then for some reason I began receiving this error:

"Member not found. (Exception from HRESULT: 0x80020003 (DISP_E_MEMBERNOTFOUND))"

I thought it was odd it worked so well then began having problems. After a while I began to receive the error while running other rules. Ones I've used everyday for years. That is when I knew something was wrong. 

I messed around with the configuration settings and eventually the errors stop. I thought I found the problem, but it has returned and went away and returned again.

I found a thread mentioning a bug that is fixed in 2019.

I'm way back on 2017, so the fix isn't going to help.

Is there anything that can be tweaked in the code to prevent the error? 

It is attached.

try this:

oUnit = ilogicvb.InputRadioBox("Select a units of measure type", "Metric", "Imperial", oCurrentUnits, "ilogic")

Putting the line in returns this error: 

'InputRadioBox' is not a member of 'Autodesk.iLogic.Interfaces.ILowLevelSupport'.
