Error from Incremental Compilation

[Altera_Forum]

Hello All, 

 I'm pulling my hair out trying to work out how I've managed to enable Incremental Compilation in the Web edition of Quartus 9.1sp1. Please see the picture.  I believe this all happened when I added a SignalTap file to the project. I've trawled through the .qsf file and removed anything to do with SignalTap to no avail.  Any help would be greatly appreciated. Brent.

I've found this issue; it was caused when signal tap asked me if I'd like to 'set my netlist partition blah blah....' because I'd selected to tap nets that were post synthesis. I pressed yes without thinking. 

 I also found that I missed a line on my qsf file that included a .dpf file in the project compilation. Removing this and all other references to partitions in my qsf has me going again.
