I have been using Flash Builder 4.5 and for some reason it has stopped opening correctly - I get the following error then it just shuts down.... :

"An error has occured. See the log file."

and if i check the log file it refers to then i see the following text:

This is incredably frustrating as you can imagine as it effectively means i cant work anymore, it is clearly some kind of problem with eclipse but i have no idea what.

I have tried re-installing Flash Builder twice and no luck.

Can anyone help with this???

Thanks !!!!

Elliot.
