ok lets take a look at the actual .exe...find it via start> all programs> JRiver...do a right click on the blue JRiver icon and then choose properties, a box opens if at the top of that box has more than 5 tabs your where i want you to be...the tab to look at is "Shortcut", what I'm looking for is "Run:" this should say normal window...now click the "Compatibility tab"...we do not want the 'Run this program in compatibility mode for:' checked if its checked uncheck it, none of the "Settings" should have a check, last is the Privilege Level, we do not want this checked...my guess is that this is checked and is causing you the problem. and or if any of the things listed above had a check and u changed them, close out of everything and shut down the pc don't just click reboot shut the pc off and turn it back on, change your uac back to default and start JR and see what happens....if none of the above were not changed then the reboot is nill as nothing was changed...I would be curious to know if any of this was of help to u....
