photoshop grayscale replaced with purple?

[aitek]

hey guys im running photoshop 7.0.1.

ive had it installed for about 6 months with no problems. came into work a couple of days ago, and my grayscale has been replaced with a purplescale?

if i create a new document, wether its rgb, cmyk, or grayscale, the shades that should be gray are now purple. no color profiles or color settings have been changed, and i checked with a co workers settings and they are the same, anyone know what is going on with this?

also i know its not my system, cause i just opened illustrator, and that grayscale is fine.

i have supplied a screenshot of the purps:
