This morning I dug right into the software and started working through compiler errors at 6:40AM. After several hours and about 500 compiler errors, I started checking to see if the error count would drop below 102 (it stops at 102, so there's an unknown number of errors beyond that). And finally, after weeks of non-stop error fixing, the number dropped to 70. I quickly fixed the remaining errors and started the program. The main window popped up, in rough shape but at least it was running!
