Old rusty!, ... I mean trusty. :smileyvery-happy:

Updating your computer's Graphic Card drivers should be done at least once a month. Outdated drivers may cause a Viewer to not run.

You may give a try with a viewer not as old and rusty as 1.23. (winks at Knowl). Try Phoenix or Firestorm. Phoenix is V1 based and Firestorm v2 based and both run fine on most computers. Also follow Knolw's excellent advice: update your graphics drivers. don't let your computer become as rusty as V 1.23! :smileyvery-happy:

My recommedation is the opposite. Updating drivers unnecessarily often causes more problems than it solves. Drivers, like any software, are subject to bugs....most driver updates are fixes for minor (sometimes major) flaws or bugs. Some are updates for new features or enhancements for existing features. But, very rarely does a driver update actually increase the capability of the card or adapter. You should update your drivers if you know some feature or capability will be added that you know you want or need for whatever it is you do with your computer's graphics capabilities. You should also update your driver if you believe something has happened that might have damaged the driver or corrupted it. It's generally a good idea to update your driver when you first get a card due to the fact that the drivers that come with the card are often the very first driver the manufacturer produced for the card.........those drivers have the most potential for bugs and flaws. Otherwise, if you have a reasonably current driver and it works for you leave it alone until there is some reason to update. The driver in my computer for my nVidia 250GTS card has a release date in July, 2010........I won't update until I see a need to update. It runs SL flawlessly.

Hello Una. Do you get an error message when you try to log in? If so, we need to know it to be able to help. You can edit your post (Options --> Edit) adding more details and also your system's specs.

Without knowing a bit more about your computer and operating system, it's difficult to know what to suggest, but there is a known bug that causes crashes with recent driver updates for  higher-end Nvidia graphics cards and newer viewers (essentially, Nvidia has deprecated some old OpenGL function calls that more recently viewers use),   See https://jira.secondlife.com/browse/SH-2409 and https://jira.secondlife.com/browse/SH-2240

There's what looks to be like a fix in the works, but, in the meantime and if that's the problem, the only work-round I've found that works consistently is, contrary to Knowl's advice, to uninstall your Nvidia driver and reinstall an older one, no more recent than http://www.nvidia.com/object/win7-winvista-64bit-260.99-whql-driver.html

That's what I had to do, and now I can run anything.  You might need to do a complete manual uninstallation of the driver; Nvidia's installer does't remove everything, and sometimes it leaves in place things that don't like newer SL viewers.   If that proves to be an issue, take a look at this thread in SLU for details of what I needed to do, but try simply doing what Nvidia says is a clean installation first.
