[TYPO3] error in ts_tidy extension

[Daniel Jefferies]

I've installed ts_tidy and it does not appear to be working.

I noticed that in the extension manager an error is listed:

The XCLASS filename-key "ext/tstidy/class.tstidy.php" was different from 
"ext/tstidy/class.tx_tstidy.php" which it should have been!

Does this mean I should change the current filename to 
class.tx_tstidy.php?  Or do I need to change something else.

Thanks

Daniel
