Focuser disappears after 1st event is finished - Version 2.4.2.x through 2.4.3.x

Desktop running Windows 7, RigelSys nFocus, SGPro, and PinPoint. This setup has been running without issues since June 2014.

Problem:
When running 2.4.2.x ~ 2.4.3.4 my RigelSys nFOCUS “is not available and disappeared”. This error has occurred as far back as 2.4.2.4, I though it was my hardware the first few times. I ran versions; 2.4.2.11, 2.4.3.3 and 2.4.3.4 the past few weeks. Each time the error occurred, it was after the 2nd filter change and right before focusing during a sequence run.

How I tested:
On my last two imaging secession, I had to uninstall 2.4.2.11 (three weeks ago) and 2.4.3.3 (last week), and install 2.4.1.0 so that I could continue imaging. Last night I installed 2.4.3.4 to get the log for sending, which the error occur after the 2nd filter run.

BTW, I notice that the focuser temperature is not displaying on the Focus module (showing “NA”) but it is showing up in the ASCOM panel that runs in the background. I made sure to make a note of it during last night testing with 2.4.3.4 I know that the tempature was showing up at one point however, I cannot truly say which version it was.
