No, I don't get any error message. Everything works fine until I use Data Assist Pages. If I haven't previously deleted the "appdata.dat" file, DW crashes when using Data Assist Pages wizard. I have to delete the "appdata.dat" file prior to use DW to work without crashing. After deleting the .dat file, DW works perfectly. As you know, when DW is closed, it stores or updates the "appdata.dat" file. This is the file I have to delete daily (sometimes more than once) every time I start to work.
I deleted all the extensions (that I have installed), leaving only Data Bridge but still the problem persists. I wish to stress that if I first delete the appdata.dat file, and then open DW it works perfectly. Do you have an update, a patch or something to correct this problem?
