[SKeeper]

Hi,all!
I used Ulead MovieFactory and Ulead Movie workshop for long time and
everytime work fine on Windows_XP-pro!

Now I dont know what happend_, but I cant anymore to load any *mpeg
files into programm!

Maybe it happend because of trojan called RapidBlaster.dr I found this virus using TrojanRemover and it report that ie_plugin.exe infected and I decided to delete it.
After deleting this virus,still the same problem with Ulead Movie Factory, programm can not to add any mpeg-video and everytime
I try to load some *mpg-file pragramm simply crashed!


Then I decided to rebuild Windows to some previous time (where Ulead Movie working fine), and it report that "NO VIDEO I/O PLUG-IN DLL available", but if I rebuild windows again to primarily time, Ulead Movie factory will not shown this message "NO VIDEO I/O PLUG-IN DLL available", but still no possible to add any video-mpg file into Ulead Movie factory and programm simply CRASHED!

What is it, please help?
