That is an Adobe Flash Player error screen and not coming directly from RevolutionEHR.  Here is an excerpt from an article related to this error:

 “The generic memory error icon was added for version 10.1 and will appear within a browser when the Flash Player has been particularly abused or is running in a very low memory environment. It is not just an icon, however. The browser will crash if it runs out of memory and Flash now has the feature in which it shuts down a SWF when a low memory situation is encountered. This keeps the browser from crashing when there is not enough memory to run the SWF. The icon is a gray circle with a white exclamation mark within it. To appear, either the browser does not get memory sufficient for its needs from the system and/or objects are being created and not released for garbage collection within Flash.”

 The latest on the Adobe forum for this issue (http://forums.adobe.com/thread/693187)  points to bad flash development which does not handle release of memory, but others argue this assertion. Adobe also states that Flash Release 11 solves the issue, but this is also not true from our experience. (This is also supported by others on the Adobe Forum.)

The first thing I would recommend is making sure that you have the most recent version of Adobe Flash Player.  You can go to www.adobe.com and download Flash Player to ensure that you have the most recent version.  If that does not solve the problem I would try a different browser.  If you are currently using Internet Explorer try switching to Google Chrome.  The memory references in the article above is the browser memory and not the memory on your computer so a different browser may produce different results.
