About a week or so ago, instead of getting the usual SL intro screen (with the mountains and the moon), I got a DOS window the lines in which would zoom by and produce the pre-caching screen and my "home" image. I'd then be logged on and would proceed on my happy way in SL. I assumed this new log on procedure was the result of switching to AutoLogOn in the debug menu - maybe so, maybe not. I wanted to switch away from it, but it was one of those things one puts on the back burner.
THEN, last Tuesday evening, after logging on successfully that morning, my SL world crashed. The DOS window popped up as usual. Then the pre-caching screen came on as usual. BUT THEN, the pre-caching screen disappeared, the DOS window reappeared for less than a second. It ran some lines and disappeared. Then nothing. I tried to log on again -same thing happened. As has happened , I'd guess, 50 times in the last four days - trying to log on after trying different "fixes" which have occurred to me.
I followed the suggested fix on the SL website support pages: delete the client, remove all files including temp files in Local Settings and cache files in Application Data. I ran Ad-Aware. I bought and ran Registry Booster which supposedly cleaned and ordered the registry ($30 down the drain?). I wrote ticket after ticket - 3 on Tuesday evening, 1 or 2 each succeeding day - to tech support in the Support section of www.secondlife.com. (More about that outsourced waste of time in another message). I have not had ANY contact with a technician in these four days. Not a word - Zilch - Nada (don't miss the message on tech support).
I considered reformatting my PC but wondered if that enormous effort would produce a successful log in. What if the problem were server side rather than client side? I would have done all that work for nothing.
My graphics card is nVIdia GeForce 7300 LE and is working fine. My computer is fairly new: Intel Core 2 CPU 6400 @ 2.13GHz running with 2 GB RAM.
If anyone can help, I would so very much appreciate it. Thanks.
Good luck.
