hey alevi,
this might be a bugger (i don't know how expansive your spreadsheet is) but if the structure of it will allow you to do so, you might go through it and remove your existing formulas now that you've reloaded the program. Then edit your way back through the spreadsheet and reinsert/rewrite them manually. This is a very hack and chop suggestion, so take it with a grain of salt.
ONLY DO THIS TO A BACK-UP COPY! Create a back-up of it first. You might screw the whole thing up. It wouldn't hurt to have an original to fall back on for reference or in the event of total catastrophe.
I can only guess at the setup of your spreadsheet, so this might be an over-simplified suggestion.
What version of Works are you running? 7.0?
If so, and your spreadsheet is of managable size (say 100-300k) feel free to email me a copy. I'll be happy to take a peak at when I get a chance. Might be a few days though.
If your data is confidential or sensitive...DON'T SEND IT TO ME. I don't want to be held responsible for peaking at somebody's financials.
If all else fails, send me examples of the formulas, and in what context they are used.
Happy to help as time allows.
LATER
