How is this Eric's fault and why must you instist on getting all ****y about it?you are still not answering my question, dear. seriously what do u get out of htis? im welcome? i didnt thank u *******.
Eric was right from the 2nd post on. There is nothing that can be done. Save the file more often to avoid issues like this. Start with the original. If he cant live without the changes he made guess what...tell him he should learn to save his work more often to prevent file corruption in case of a system error. Everyone who uses a PC knows this basic fact.
Also learn to type. It is horrific trying to read some of this. htis? What is that? "cmoptuer editing a larege file" There is a thing called a spell checker.
