Last night Flash CS3 started crashing upon loading, and
The Adobe support page was no help. I tried calling and was on hold for about an hour then gave up because my cell phone was cutting out. I spent hours on the internet searching for suggestions, which either didn't work or weren't doable: (for example, a few sources said the Franklin Gothic Font often went corrupt and to remove from my computer. I deleted it, but seconds later the font reappeared in the font directory.)
Then I tried reinstalling. . After about 40 minutes the popup notice said it was done, and, by the way, AdobeCS3 couldn't be installed.
What finally did the trick was carpetbombing (okay, completely uninstalling) the original and restoring it from scratch.
Added- a picture of my niece throwing at fit.
