Which version of "CW Classic"? If it is 7.1 or prior, then you've got a problem.
CW changed the ABI in 7.2, breaking pretty much all previous example code (that used any assembly). If your "CW Classic" is 7.2 or after then it should be OK. If prior, then read this first and follow the links:

Options are:
1 - "Archive the old build environment" (old OS, old CW, old uTasker, old code) and run it in a VM on your new computer,
2 - Update to latest uTasker (it shouldn't be all that different to the user code), or
3 - Manually rewrite every assembly function in the old uTasker code and every C source that depends on the ABI. This would be very difficult.
If this is a "Hobby" or "Educational" project then you can license uTasker for free. If it is a commercial project, then the cost of uTasker is about 2 to 4 DAYS worth of what a Programmer earns, so if it gets the job done earlier it has paid for itself.
