Same thing happened to me. My account got disabled after like a month. Then they constantly started emailing me offering to open it up again for $29 for a year. I thought it was a sweet deal,
When my account expired, I was not notified (e.g., by email): I just went to connect one day and it said I was expired. That connection attempt was less than 40 hours from the end of the previous period, and I had not happened to try connecting during that period so the actual cut-off might have been less than the 40 hours. Certainly it didn't do anything quirky like it has done to you.
