I've had the following problem with NVivo. I use NVivo at work but sometimes also need to work from home. So I save my NVivo project on my external hard drive and then open it on my laptop at home. However lately this doesn't work anymore. When I try to open an NVivo project, and then click on Sources –> Framework Matrices and then select one of my matrices, the matrix first of all opens up but looks odd, because on the right where the source (i,e. my interview transcript) is supposed to be, it is blank. Then when I try to click into one of the cells, NVivo immediately crashes and my computer tells me the program is no longer working.
