Accessing PC-Doctor 5 on laptop

[patient]

Hi
I have a Lenovo laptop 3000 C200 on which PC-Doctor5 was already installed when bought 4 years ago and has always worked fine.

Recently, however, when I try to open the programme I get a message  "java.lang.NegativityArraySizeException" and can get no further

Please can you help me
