I have built a database in Access 2007, managing bookings and staff allocation for a disability service. Forms driven by macros select parameters for reports. Last night the macros all ceased to work, with error 2950. The Microsoft site said that this is a security issue and to place the database in a trusted location and enable macros. This was all already in place and the database has worked well for months- nothing within the database had been changed when the errors started occuring. I have patched the database back together, by importing queries, forms, reports, macros etc from a back up and the tables from the current version, but I am anxious to avoid a repeat of the whole problem. Any advice would be appreciated!!
