I've kept excellent records of all activities relating to my computer. I have them backed up on three external hard drives as well as on DVDs.
However, I don't know why, but I couldn't find the records for the 2120 problem.
I went to the Rosetta Stone site and reviewed my history and there's nothing there about the 2120 problem.
As it was 2 years ago, I've forgotten exactly how I solved the problem, unless it was one of those that just "went away".
In fact, and I'm sure you've done this, I entered "2120" into the search box at Rosetta Stone and came up empty. Hmmmm.
I will tell you that they're excellent when it comes to chatting. You could try that.
I'm not sure of your nationality and I don't want to insult anyone (except the CEOs of American based multinational corporations, of course), but, as American corporations enjoy putting Americans out of work and paying Indians and Hispanics who live in foreign nations 1/4 of the wages they would pay Americans, which helps neither, I've had some trouble understanding the people who have helped me.
On the other hand, they've always been pleasant to work with and very, very helpful.
Sorry I couldn't be of more help.
