Get Opentaps on our server restarted

We recently has our server which had an opentaps (slightly customised) production running. Although we have recently moved our main website fom opentaps to another hosting and to magento we still have open orders and another website on opentaps, also we need the historical data. A week or so ago the server went down due to motherboard failure. After the replacement we could not get the server back up initially until some work was done on it. The server is now up but we cannot restart opentaps. All other services are running, (virtualmin, webadmin, websites not using opentaps, apache etc). However when we try to use ./[login to view URL] in correct directory we get a java error as it tries to set OFBIZ_HOME to the current directory and [login to view URL] does nothing. So I cannot restart opentaps and resume operation of my setup. There are 2 important things we require. One is backup or no loss of the historical data (database), so we could do with backing this up prior to any work and somehow receiving an offline back up of this. We need the info for accounts etc. The other is to get the current production running so we can finish off any orders and in the next few weeks move the rest of the websites from there and once backed up shutdown the server. The motherboard failure was very bad timing for us. This job would suit someone who know opentaps very well and I am hoping it will be a fairly simple job for the right person. We do not have have much money to throw at this so really am hoping its a quick job now the server is up. Thanks for looking!
