After I record ,stop ,then open where it is saved but nothing in there(camstudio)

after record ,i cannot open it or may be it cannot record(camstudio)

Cam Studio has an option for automatic file naming that names files by the date and time and places them in your Cam Studio folder. Look in the folder for files with a long string of numbers that represent a data and time with an AVI extension.

To rename the files as you save them, go to Options/Program Options/Name of AVI file and change it to "Ask for file name."

Ask_Sean Says, try unistalling it and reinstalling it that might help? or there should be a folder in your documents "camstudio clips" and if it's not there then eithier you cannot record or something wrong with your format, maybe try installing the lastet verson?
