If you installed the interim update KB2581545 after the issues with Rollup 4, you must first uninstall this interim update before applying Rollup 5. You can upgrade directly from the v2 release of Rollup 4 or the original released version of Rollup 4 (or from any other Rollup update for Exchange 2010 SP1).
No issues with this Rollup update have been reported yet.
The next update rollup is scheduled for release in October 2011.
(Rollup 5 for Exchange 2007 SP3 will be released soon too.)
