Cubasis 2.0 crashing mid-song


I have been using Cubasis 2.0 on a Windows XP laptop, since 2001, without any problem whatsoever.

I recently got a new (refurbished) Windows XP laptop with 2GB of Ram (twice the memory I used in 2001) and it keeps crashing mid-song.

I assumed the problem was a laptop fault so I tried it on a Windows 7 lapton in both Windows XP Service Pack 2 Compatability mode and Windows XP Service Pack 3 Compatability mode, and I had exactly the same probem witht he software crashing mid-song. I do not know why this is happening or how to remedy the problem.

Without access to Cubasis Go my entire archive of over 100 origina songs, is totally lost.

Can anyone help?
