Yep....same problem. I filed one return and it worked, and five minutes later (and now hours since) it says it cannot find and internet connection. I obviously have a connection since all other sites work fine, and this bloody program will do an update....and then says it has no connection at filing.
I have used this program since it came out and it has given me increasing problems over they years. This year is the last time. I am now looking at printing and hard copy mailing one of the two returns.
The program also failed to import my return from last year... something about using a purchased CD vs a download version. What a bunch of crap.
