seems you are in lyx 1.3.5 which allows lyx to accept a file that has a document class file, such as article.sty, which you dont have on your machine or which lyx is not aware of.
You may want to run texhash at the command line before doing anything else. Then restart lyx and see if there is any success. If not go to the menu item Layout and follow it through to document. When the Document Settings window opens the first item is Document class. Read the name, go to ctan, load it and put it in some suitable directory in texmf and run texhash. If you then reopen lyx it should be alright. good luck samar ----- Original Message ----- From: "Rowan" <[EMAIL PROTECTED]> To: <lyx-users@lists.lyx.org> Sent: Sunday, January 30, 2005 6:00 PM Subject: missing a file, can someone help me > When i try to open up a few different templates, lyx keeps informing me of a > Textclass error.
