Thanks all for the reply. Connections have already been established prior to using the wizard and the database has been set up and populated with data. I am able to establish the connection from the list and start to assign the dynamic values and there abouts DW will crash and quit.
An addendum to the situation: Tried disabling / removing all extensions again, dropped the *.dat file and reloaded DW, but was getting popup errors that WA files were not found even after removing all of them and dropping the *.dat file before loading. At this point i thought something may be corrupt in the DW files other than the cache so i uninstalled DW and re-installed it clean then started adding in the extensions again. I installed Data Bridge then eCart and am pleased to say so far so good. Noticed there seems to be an issue with WA Google ToolKit (could be my version) and the newer Data Bridge.
Can't say for certain what the issue or even the fix was, i suspect something went awry during the initial removing of the older extensions and caused a corrupted file somewhere (since DW was looking for WA extensions with none installed). Hope all of that helps someone else, quite the frustrating issue.
