[amelia] convergence issue

I am getting the following error when trying to run Amelia: 1 Error in eigen(thetanew[2:nrow(thetanew), 2:ncol(thetanew)], only.values = TRUE, :infinite or missing values in 'x' I've read through the list and have tried the fixes that have been suggested. I removed about 15 cases when participants had less than 10% available data. I've also tried lowering the tolerance. I am assuming that at this point I should think about variables to remove. My data consists of 89 questions for an epistemological beliefs scale I am trying to create. Are there any suggestions as to how I should go about choosing questions to remove? I've checked the correlations and there seems to be no multicollinearity. Any help would be greatly appreciated!
