I may have posted similar issue before. Nevertheless, here it is again.
I made an exe using 8.2.1 and ran it for some time. Then I reverted back to the original exe (backup exe) that was in 7.1. Now the original exe in 7.1 does not read/write properly. Also there seems to be a problem populating the variables (the system reads the variables from text files on the network).
Please help!
