Hello Miss YaraAlexis
The same thing happened to me, and I still cannot get on. But, I think I know why.
On the second life grid it says this:
[postED 7:40PM PDT Aug 15, 2011] Rolling restarts for regions on the main Second Life server channel will be performed on Tuesday, August 16th at approximately 5:00am PDT. Please make sure to save all builds and refrain from making purchases during this time.
Have a nice day, and I hope you can get back on
