change of base year - VAR problem

Hi!

I just changed the base year (base1) from 2000:1 to 2005:1 in

{%e}={%e}-@elem({%e},%base1)
{%h1}={%h1}-@elem({%h1},%base1)
{%h2}={%h2}-@elem({%h2},%base1)
{%x1}={%x1}-@elem({%x1},%base1)
{%x2}={%x2}-@elem({%x2},%base1)
{%y1}={%y1}-@elem({%y1},%base1)
{%y2}={%y2}-@elem({%y2},%base1)
series p{%pd}={%x1}-{%x2}

and tried to do the VAR forecast. (It worked with 2000 as base1.) There is a Zero in the base year...

Now I get this error message: "Insufficient number of observations to estimate 20 coefficients per equation in VAR ... "
(I tried it with less coefficients...same error but lower number)

That´s how the VAR looks like:
base=138
smpl @first @first+!base+!j-1
var mvar.ls 1 2 {%dx1} {%de} {%dh1} {%dpd} {%dr1} {%dr2} {%dy1} {%dy2}@ c dpoil dpoil(-1) dpoil(-2)
smpl @first+!base+!j @first+!base+!j+3

mvar.makemodel(m1)
m1.scenario(n,a=_0) "var"
m1.solve(s=d)

I wonder why it does not work, some help would be nice.

Probably best to post your workfile, and the full program.

Some time series ranged from 1970 to 2004 ... that´s why it was not possible.
Thx.
