win 7 blender never a problem, now wont load, period.

i have been using blender for over a year now, never a problem. this morning, i was working with an .svg, i imported into 2.49, saved as a blend, closed it opened it up in a 2.55 build. It was the blender.org d/l edition of blender.

i converted my curve to a mesh, removed doubles, smoothed, and colored i dont recall at that point if i went to reboot, or if it crashed itself, (which happens every 15 mins anyway).

the point is, when i go to open any build now, beit a graphicall nightly luxrender build or 2.46, 2.49b, or 2.55 i get about five seconds of console screen, and the milky screen of blender death.

please let me know if i can give any other information to help.

I really appreciate any suggestions, or links, or direction, i’m jsut sick of staring at google and not knowing what to search anymore

thx

if this is in the wrong place please let me know so i can go where i need to be.
