Received notice yesterday of Service pack update, which I did this morning. Would not "run" as other updates did, so ended up saving it to desktop and then downloaded no problem. Once downloaded I am now no longer able to open any other modules other than the GL.
BR gives me "Error External exception E06D7363 occurred when attempting to check existence of A/P global", while the other modules reference the E06D7363.

Can I revert to last Service pack?
