Sorry to hear that Eye-Fi Helper is crashing on you. We'd like to help, and we don't always check the forums on a regular basis so it would be fastest to contact us directly.
Please email us at email@example.com
, refer to this thread and include your Eye-Fi Helper log. The Helper log locations are listed here: viewtopic.php?f=30&t=5776
and the log file will be called "EyeFi.log" or just "EyeFi". Put "Attn: Jason" in the subject and I'll take a look. Please also confirm the email address you entered when you sent the crash report(s).
