FAQ - SuperMemo UX


I'm trying to install "Polski Bez Problemu+" on my laptop with Windows 7. It says "the installation needs Windows Media Player 7 or a newer".

This course has been released before Windows 7 and is not fully compatible with it.

To workaround it download and launch the following patch:

and start again installation of the course.

After several days of using Supermemo there appears an error 'Cannot estimate a new factor' which prevents from further learning. Can I fix this problem without lost of the data?

Please replace the sm8opt.dat file with the original one from the DVD-ROM (info directory). Please uncheck the 'read-only' attribute for this file. The learning process won't be changed, but some data will have to be rebuilt.

After the program has started an error appears: 'Cannot open player device MMSYSTEM266. The device could not be loaded. Verify the driver is installed correctly.'
This error informs that the system has problems with the sound drivers. SuperMemo uses default Windows drivers. To fix this problem you have to reinstall Windows Media Player. You may use the original Microsoft Windows Install CD-ROM or you may get the newest WMP version from www.microsoft.com. You may also reinstall the Internet Explorer. Don't forget to select the 'Windows Media Player and additional codecs' option during the installation.
Windows XP error - 'C:WINDOWSSYSTEM32AUTOEXEC.NT.....'

During the installation process in Windows XP occurs the error 'C:WINDOWSSYSTEM32AUTOEXEC.NT - This system file cannot be used to run MS-DOS applications. Choose Close to terminate program.'. This means that Windows does not support 16-bit programs that require unrestricted access to hardware. If your program requires this, your program will not work in Windows XP. Microsoft Company diagnosed this problem and published a solution in a 'step-by-step wizard' - click here to learn more about it.

How can I start learning vocabulary from a selected section only?

First of all you have to open the 'Contents' window, then select the section you want to learn and click the 'Review' button. This option is not stored by the program, so if you want to learn this section again, you will have to repeat this procedure on every start.

The second way to do this is to move the chosen section to the top of the table of contents (in the 'Contents' window). Then you have to sort the entire collection according to the order in the tree (option: File: Reset: Sort pending by contents). This method will change the order permanently. Notice that the 'Advanced English' collection is sorted by difficulty. We recommend to resort the entire collection by difficulty after the learning process of the chosen section is finished (option: File: Reset: Sort pending by ordinals).
