Cant Run VC Applications with Flex2

Hi to Everyone!

I need help with a permanent problem in VC.

We had a couple of VC aplications running without problems but now, after installing 7.0 SP23 Version they didn't work anymore.

I did some other simplest tests and verified that always do the same: Can compile & deploy the application but can't run it (an exception appears). "Last 24 Hours" trace presents this message:"CompilingException: Error occurs during the rendering of jsp component"

What's wrong?. Any Help will be kindly wellcome...

Thanks!
