Note that there was a problem recently in the program option "Automatically open last project on startup", especially when the last project file was stored on a file server.
We corrected this issue recently in one of our program updates. You can download the latest version from our StormNET download page at:
StormNET Downloads, STORMNET Software, stormnet tutorials, and stormnet documentation
Also, you might want to "uncheck" the above program option. Please let me know if you continue to run into problems with this.
