I am having an identical problem using EMC 9 as reported in a similar post in the EMC 8 forum. This is a duplicate of a reply in the EMC 8 forum since strictly speaking I am experiencing the problem in EMC 9 even thoguh it is the same as experienced in EMC 8.
I have been through many posts and have complied with all of the suggestions/recommendations set out in the various posts that I have researched but always with the same error occurring.
My system is as follows:
DELL Inspiron 9100
NEC DVD+RW ND-5100A
WINXP SP2, IE6
BIOS and all firmware is at the latest release.
The system was supplied with Sonic MyDVD 5 and RecordNow 6.5 and worked when I first got it. After a disk malfunction I rebuilt my system and everything worked fine except the installation of RecordNow 6.5 and Sonic MyDVD 5 from the original disks. I decided to buy EMC 9 and have cleaned out the Sonic stuff and on many occasions gone through a completely (to the best of my knowledge) clean install of EMC 9. All functions of EMC 9 seem to work OK EXCEPT RecordNow Data, RecordNow Copy, RecordNow Audio - so I guess it's just RecordNow that is having the trouble.
When I invoke RecordNow it displays the splash screen and seems to start up Roxio Central33.exe but then gives a dialogue box with no error shown. On closing the dialogue box it then displays "Invalid Pointer comerror 80004003". If I try to invoke RecordNow a second time it does nothing. Stopping the Roxio Central33 process and restarting RecordNow it reverts to displaying the splash screen and the comerror.
Any help would be much appreciated since I am progressively going mad trying to get it going.
