near singular matrix and estimated Panel ARDL

[kafazi90]

hello, this is my first post. if misplaced, I'm sorry. im using Eview's 9.5 Student Version.

I was working on a thesis by using ARDL panel. when I enter the data into the Excel program is not a problem.
when I do a regression ARDL had appeared a near singular matrix error. data I use is 31 cross 9 time series.
but using fix or random can do.

optimal lag selection with 4 can not be done. what I did was right or wrong?

but when I change a series to cross data when the estimated short term could be done.
but that appears is the series. My target cointegration to cross.

thank you
