PANIC SITUATION :(

I had created a baseform class. in that baseform class there were few custom methods and few properties defined. there are many forms based on this baseform. SUDDENLY i can see only NAMES of these methods and NO CODE in them. and obviously ALL the forms have stopped working. the properties with their values are alright. the code in the method is no more. ofcourse i have not erased them. and they were here just so far. for gods sake, i can not even rewrite all of them. what is this? what do i do to bring those methods back? if this is memo file problem, any salvage utility available on net? am i supposed to loose my code THISWAY? and is this what they always say as unstableness and insecureness of VFP? How will i deliver the project tomorrow? i am under a panic situation. HELP.
