connecting problem on gotowebinar

Recently, I've been learning to use gotowebinar so as to be prepared for our future webinar.

 

My 7-day free trial started from 5th, July, and will be expired on 16th, July.

 

I subscribed the $249/month plan yesterday(7/13), and the function was all good then.

 

However, I've kept failing to start a webinar today due to "Internet connection problem."

 

I'm sure my Internet works well.

 

Besides, I use another account to get free trial and I can still start a new webinar without any problem.

 

Therefore, I think something must go wrong with my original account.

 

I've searched a lot on google, but didn't get helpful information.

 

Does anyone have the same problem or know how to fix it.

 

Please kindly help me solve the problem asap.

 

Thank you!
