long time working cgi-scripts with a problem

I have my machine transfered after the purchase of the hosting company to a new hardware.I have there 4 perl 5.10 cgi which worked perfectly. The hosting support tells me they are blocked by 5 reported bugs. I need some expert to have a look and correct these.

I can provide the files.
This is urgent (02:00 now over here).

Thank you for the help.
