I updated to the newest version of 5.  When I select an image and choose "upload" (am using the uploader for SmugMug) after 30 seconds or more, I get this message:  
Unable to upload because: Timeout waiting for account parameters from server. 
 
I can't choose a gallery (only one is offered and it isn't the one I really want to use but it would do if I could get the upload DONE).  Near the lower section the information is:  "opening connection" and that doesn't change.  I've checked with my internet provider (in case there was a signal issue and there wasn't).  I can do all other normal "stuff" online.   I did a SmugMug "hero" chat yesterday and their end of the transaction seemed normal and stable  Their suggestions were good, I followed them and nothing has changed. I've used IE and Chrome.  I've cleared ALL cookies.  I've reset my router and modem. Any suggestions.
