PLEASE HELP! Afaik, it was an 11mb file so it wasn't big.
And it's due today
I hope you have a copy of your file that is not corrupt.
Cn you try once after cleaning your cache and preferences? Troubleshooting 101: Replace, or "trash" your InDesign preferences
Also, which plugin are u referring to?
I'm presuming i need to reinstall indesign then? Since it won't open at all
No, start by resetting preferences as shown in Aman's link:
There are two ways to do it. Try one, restart. If it doesn't work, try the other, restart. Come back and let us know.
