System.NotImplementedException error

[markintheworld]

I am trying to install StruCalc 8.0 http://appdb.winehq.org/objectManager.p ... &iId=28028 on my Mac.

This is my first time running wine (noob alert!). I have overcome many obstacles (I'm about 10 hours into the process, with great help from our friend google) but finally got stuck, and must reach out for help.

I have been following these instructions:
http://www.davidbaumgold.com/tutorials/wine-mac/

I installed MDAC 2.8, Jet 4.0 and Mono 2.10.

I have gotten as far as the opening setup screen on StruCalc, and ran into this error:
Timer1
System.NotImplementedException: The requested feature is not implemented. at StruCalc.frmAuth. Timer1_Tick (System.Object sender, System.EventArgs e) [0x00000] in <filename unknown> :0

I am stuck at this and not sure where to go from here. Any help would be appreciated...

Thanks!
