not about guild wars, googled it and nuthin

ok, i am having serious problems (well not to bad).

it all started after i downloaded and ran eraser. i after it finished i can no longer look at any txt documents (where did all the words go?), and in other instances i get GDI Error: Can Not Compute Text Size.

i am trying to contact http://www.heidi.ie/eraser/ where i got the software for help as well.
here is the post i made:

GDI Error: Can Not Compute Text Size.

that is the error i am recieving on differant (but not all) programs. all my fonts are screwed up as well. i just downloaded and and used the program (eraser) on unused disk space on my c drive for the first time today. any help please?
i can't play any of my mp3's because of this (i use ashampoo media player)

Well if you are using XP you can try to use system restore and restore a point prior to using the eraser program.

maybe, if i hadn't disabled it.
*smacks forehead*
woe is me, woe is me

but i thought that maybe i can use my xp disc to repair windows?

ok, i restarted and everything is back to normal (except my settings)?!
