I get the following error when I run some reports:

"Internal error. Unsupported major.minor version 51.0"

The ones that throw the error are displayed via a process that is an operation on a form. Any reports that I run from the VP main navigation menu run without a problem (don't know if that has any bearing on the problem but thought it worth mentioning) All of the reports and operations worked in versions prior to 5.8. Here is what the AwareIm Server output looks like:

	java.lang.UnsupportedClassVersionError: Unsupported major.minor version 51.0

Come Monday morning I'm going to be in the thick of it with this one as I will have users that will not be able to run reports. Any help will be greatly appreciated.

Thanks
