From Larry Weinberg; "It seems there are two or three people with your same problem. We'd like to try and determine what it is. Attached is the older Interlok system driver for Windows 98 and Me that may fix your problem. Please let us know if it does. Make a backup copy of the newer driver that has been installed in your windowssystem folder. (Tpkd.vxd) Unzip this file and place the Tpkd.vxd file in your windowssystem folder. YOU MUST THEN REBOOT your system. Then try Poser again. If this works, please let us know immediately! Sorry about the problems." ------------------------------------------------------------------- Tried the above and it didn't work.. same blue screen. ------------------------------------------------------------------- Larry Weinberg wrote; "The other person who had your problem was helped by using the old driver. That person was on Windows ME. Is it possible that you may need to update your Windows 98 operating system to the latest service updates ? We have not had these problems on Windows 2000 or Windows XP or on our Windows 98 machines. It is possible that a special virus checker could be conflicting with the Interlok driver. Also, there have been some cases that an HP printer driver can be the cause of conflict. Thanks for the positive thoughts. Hopefully we can find the cause of this quickly." ------------------------------------------------------------------- I uninstalled P5 again and made sure that the older driver was installed... Don't know the date on the driver that I started out with before installing the patch. Should check Microsoft for any 98SE updates (can't imagine that there are any but..) Now P5 runs again... no patch installed.
