Hasta La Motion!

:(Dear friends after using Nuke 64 for sometime with Windows Ultimate 64 I witnessed permanent file association problem.For example I create a project and I instruct the Write node to perform a render of say a 100 image sequence asking it to output in jpeg format.When I open the created file I get the 100 image sequence in anything but jpeg.The created images in the output folder are virtually no name…windows refers to them as file in the File Type column.Premiere or other NLEs are unable to resolve the file type and won’t do an import for further process.I ran a preliminary search on the internet and they say it’s probably a registry problem.They propose to download programmes like PC Mighty Max 2010 to resolve many problems along which and file association mismatches.It seems that I can go no where from here…It’s urgent for me.Can you help?Please!By the way I hope you enjoyed your Christmas and I wish to all of you a happy,prosporous and creative new year of 2011:)
