Error in Opera

I have installed Opera and have two problems.

(1) How to I make it my default browser
(2) I keep getting and error that says

-ERR Authentication failed
Type:" Incoming (POP)

It then asks for my Username and password.

I have entered both as the ones I use with my ISP and it is rejected
I have registered Opera and my ISP says the msg is not from them

Antyone know if there is an Opera PDF I can download

 

(1) Default browser option is under Tools > Preferences > Default Application. Check for Opera to check if it's default on startup.

(2) This usually means something in your mail setup isn't right. Go Mail > Manage Accounts, and make sure server names are correct. The incoming Pop server should be mail.yourISP.net, or pop.yourISP.net, or something similar. Check that the correct name is in there, and double check all other entries in mail properties.

Opera has a good help forum. http://my.opera.com/forums/

Good luck! Opera is wonderful when you get it figured out.

 

I dohave Opera set as the default browser and all the protocols checked that i want it to read. (not my graphics)

I also went into the explorer>file types and made sure that all the ones applicable will use Opera --- but they don't
==================
My smtp and pop addresses are both mail.optonline.net.

and they were set right
