The current status of VDSLM is a general availability public ß

This is a temporary bug list:

Robert N. (Thanks Robert for the feedback) reported the following error when running VDSLM.

This error is the result of an overrun condition. VDSLM use a timer to initiate acquisition sequences (run). When the acquisition thread executes it waits for the 2wire gateway to respond to the request. If the gateway for some reason takes longer than the interval timer to respond to the first request the timer will issue another request before the gateway finishes the first resulting in an overrun.

Solution: Ignore the error and increase the interval timer. Next build of VDSLM will include overrun error report to the logs instead of a message box.

Windows-7 32 and 64 bit installation instructions.

Over the weekend we received one report stating that VDSLM is not working in Windows-7 32 and 64 bit We have confirmed this and found a solution. To make VDSLM play nice under Windows-7 32 and 64 bit VDSLMonitor has to be running with extended privileges. To accomplish this first uninstall VDSLM and clean the registry of all VDSLM entries 'HKEY_CURRENT_USER\Software\Dohrenburg Systems' and 'HKEY_CURRENT_USER\Software\VDSLMonitor' then reinstall VDSLMonitor.

Select the Desktop shortcut and right click on 'Properties'.

In the properties window select the 'Compatibility' tab.

At the bottom of the page click on the 'Change settings for all users' button and in the 'Compatibility for all users' page check the 'Run this program as administrator'

Click OK in all open windows.

Now run VDSLMonitor again and if you still have problems give us a call.
