Brother HL-645 Printer Problem

Installed software for this printer but on re-boot a window pops up called "Msgsrv32" with an "illegal operation, will be shut down" message. Closed that window and tried to print something and had a window pop up called "Rundll" with the same "illegal operation" message. Printer starts up on booting computer but can't do anything with it. This printer was installed about a year ago and worked fine then. Wondering what's happening here and how to correct it.

Are you able to boot the computer?
If not try booting the computer without the printer turned on and see if it does the same thing.

What version of the software did you install?
Is it the most recent version? -- The most recent version is 3.00 and is written for the brother HL-630,645 and 655M.  The file size is 552kb.  The link to download it is:

Hope that helps.

To jrhelgeson: Thanks for your reply. Yes, the computer boots ok and on the label of the disk that came with the printer all it says is version "A". This printer is 3 years old so I expect the version you talked about is better. I downloaded it and it's setting in a folder as a zipped file. Where to I unzip it to?
Follow these instructions given to help you install the update.  This was also taken from the brother website:

Text follows:
Windows 3.1 / 95 / 98

1.  Please make a temporary directory on your HDD to save the downloaded self-extracting file.    e.g. C:\brodrv

2. Click the model name to start downloading.

3. Select the temporary directory as where to store the downloaded file.

4. Extract the file.  (by clicking on it)

< Windows 95/98 >
Double click on the file in Explorer, or click [Start], select [Run]. Then type the temporary directory and the file name  (C:\brodrv\xxxx.exe). Then choose OK button.

5.  Install the upgrade driver.

< Windows 95 / 98 > 
Click [Start] in Windows 95/98, choose [Run], type [SETUP], and then press the OK button.
e.g.. C:\brobrv\setup  Or, click [Start], [Settings], [Printer], [Add Printer], then please follow the instruction.
