This is my first post to this forum and it is a bit OT. I have just installed NIS 2004 and ran into grave problems.Before I had no problems with NIS 2002 or Vue4. After the first installation of NIS 2004 I had problems running both NIS and Vue4. NIS refused to scan and Vue seized up particularly when editing the terrain. After the seize ups there was a dominos effect with Poser5, OE and the optical mouse until I had to shut down the computer manually. There seemed to be a "fight" over module kernel32.dll.I got a message that Vue had caused an invalid page fault in that library at 018f:bff714ac. Symantec gave me loads of documentation to deal with what they concluded was that NIS had been installed with one or more corrupt files. I followed instructions and re-installed NIS cold. NIS running OK until I ran Vue, had same problem but the message box was empty apart from the close button and NIS would not open until I rebooted. I un-installed NIS - Vue 4 ran OK. I then un-installed Vue4 and re-installed NIS cold, running OK. Next I re-installed Vue4 normally again NIS ran OK but Vue 4 seized up and then NIS would not run. I have sent another email to Symantec and am awaiting their reply and will send a copy of this message to e-on software but wondered if anyone else had met this problem and to warn others of the possible conflict between NIS 2004 and Vue4 both original and the latest versions.
