I imported a very large pcap file (1.76GB) into Packet Builder v1.0. I was able to send selected portions of the imported data. I would get an "Out of memory" error if I tried to send all packets. I closed Packet Builder. When I try to restart Packet Builder, it gives me an "Out of memory" error and crashes. I think it is trying to reload the large amount of data that was previously imported. I tried uninstalling and reinstalling the app (with a reboot), but it still does not restart. I even deleted the Software\Colasoft key from the registry's HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER, made sure the Colasoft Packet Builder 1.0 folder was removed from C:\Program Files, and then reinstalled. I get the same error. Any ideas?
