excel 2000 - corrupted data
 

I have been using Excel (Word prior to that - data
transferred to Excel when advised that Word had problems)
for over 2 years to store information (updated frequently)
which has become corrupted (somehow) when viewed later.
Apart from fixing these errors (when found) i am fighting a
losing battle to maintain accuracy of my records. I have
had to resort to using 'SAFE' mode to do so (which seems to
be working) however, whilst in 'SAFE' mode i cannot access
Mozilla Firefox (i've had Internet Explorer problems -
slow response etc). Does anyone have a solution that will
keep my records safe without using 'SAFE' mode ? Would a
later version of Excel help or would the problem be
transferred with the upgrade ? To my knowledge i have
never had a 'virus etc' affect my system. The only known
reported incidence was caught & destroyed by my Anti-Virus
less than a year ago. Note : Microsoft Help & Support
didn't help as operators had never heard of this problem.


thanks
John
