Window Me and real mode DOS Application

I had upgraded my office network with windows me
from windows 98 SE, now our dos network application related to finance which used to work
hassle free on Windows 98 started giving problems in windows me especially when printing reports gives error messages indicating insufficient memory.

I came to know that in windows me microsoft had
disabled real mode dos addressing.
Is their any tweak available to address this issue
so that my dos application will perfom hassle free
windows me.
Already I had experimented several methods but all
resulted in negative result.
